We'd need to know stuff like what the gain of each stage should be (we
already know the gain of the last stage is 1...), whether the first two
stages use matched pairs in a single package or discreet components,
etc...
^^^^^^^^

Actually, their components have a reputation for being terrible
busybodies....

Double a penny every day for a month and what do you get? Over one 10 Million $! That's the power of exponential growth, and the Internet is the one medium that can harness that power... for just $60!

ContagiousPlan fully exploits this phenomenon to help generate Fortune from your website!

So how does this system work?

Our system is similar to others you may have seen on the Internet with one major difference... our system guarantees Wealth through your website! The concept is simple; at the bottom of this page you will notice 6 members boxes.

NO RISK, BECAUSE THE NEW MEMBER PAYS YOU DIRECTLY. YOU DON'T WAIT FOR PAYMENTS FROM THE COMPANY.

When you sign up, you will receive a website just like this one with your Box in the #1 position! The member that was in the #1 position will move down to the #2 position, the 2nd to the #3 position, and so on with the 5th member being taken off of the page.

When someone signs up from your website, their membership will be placed in the #1 spot with you moving to the #2 spot, the 2nd moving down to the #3 spot and so on. By the time your position reaches the #5 spot, you will have noticed an amazing amount of Wealth earned!

How do I get guaranteed earning?

http://www.contagiousplan.net/club10/mspitler.htm

When someone signs up from your site, they must first click on your Box which will open a new window leading to your payment page.

Each Box will have to be clicked on to pay the 6 upliners

How much Wealth can I expect?

Lets be extremely conservative and assume that your webpage and everybody else's pages only get 10 sign-ups, when you reach 5th level it will look something like the calculation below:

CONSERVATIVE EXAMPLE
10 people sign up from you: 1 x 10 = Your earn 10 x $10=$100
10 people sign up from each of them: 10 x 10 = Your earn 100 x $10=$1000
10 people sign up from each of them: 10 x 100 = Your earn 1,000 x $10=$10,000
10 people sign up from each of them: 10 x 1,000 = Your earn 10,000 x $10=$100,000
10 people sign up from each of them: 10 x 10,000 = Your earn 100,000 x $10=$1,000,000
Total: 100+1000+10,000+100,000+1,000,000= $1,111,100

http://www.contagiousplan.net/club10/mspitler.htm

This system works amazingly well on the Internet. There is nothing to slow it down. You can setup your ContagiousPlan webpage today and have 5 or 10 sign-ups within a few days! With it being so easy to join you could literally have over 50,000 sites displaying your Box within a short time!

FAQ

1. I don't really understand this. What exactly do you want me to do???
The steps to your success are simple:
First of all, ask yourself if you would like to make some extra money with little effort (anyone would want that, right?)
Second, if you answered yes to that, ask yourself this:
"Would you rather go it alone and have to do all the work to get a return on your investment OR would you rather work with a group of like minded people who help each other earn a return on their investment?"
If you answered yes to that, you should not hesitate to join us right away. Start from the Home Page, 1st pay your sponsor, the 1st member, 2nd, 3rd, 4th and 5th member. Now you are ready to sign up.
When joining, you will be asked to choose which MLM opportunity downline builders (Sponsor) you would like to join. You can select any or search randomly.
After you have joined, you can just sit back and wait to see your downline grow, OR you can do some sponsoring yourself to move things along a lot faster!

http://www.contagiousplan.net/club10/mspitler.htm

2. I still think this is very suspicious
We are aware that this seems strange to most of you. You think that this is a pyramid scheme or a fraud that will make you lose your money. We do not collect the fees from members, set their guidelines or pay the commissions earned. Each member pays his upline directly without companies involvement.

Multi Level Marketing is a serious business strategy to put a company in great profit. By using a group of independent contactors they have a major savings on advertising. So, they pay YOU to advertise and sell their product for them. They use this savings to pay you a commission on your sales and the sales of your downline!

The majority of people that get involved in MLM or Network Marketing (95% is the latest figure published) don't recruit a large enough downline to get a return on their investment. By gathering all the people that cannot sell or recruit, we end up with a huge mass of people who end up losing their investment. Here is where Contagious Plan enters. By banding together and helping each other, everyone can get a return on their investment with just a fraction of the work and cost it would take alone! Everyone wins!

3. I don't see why I should join you

Okay

You will probably forget about us in a couple of days. You did NOT make any money and you did NOT lose any time. I guarantee you that you will be seeing our name around the net and our members talking about the club. Maybe the next time you see something about us you will decide that a little help would be nice. So you visit again and this time decide to sign up.

You visit our Home page, read the message board and see that other people are excited about what we offer. You wait for a few weeks but then you lose confidence in our system, so you leave. This time you did NOT make any money but you DID lose some time. Again in a few days you forget about Contagious Plan.

Then you see something about Contagious Plan again. You decide to give it another try. You visit the member's area, read the message board and mail a few people to hear their opinion about the club. You give it a little more time and suddenly you feel excited. No doubt about it, all these people are here to make money! And in the message board there are people who actually have made money and who participate again!

A couple of months pass and suddenly it's your turn to join the MLM company. You hesitate. Should you really risk the investment of say $12? After thinking it over, you decide to go for it. After all, $12 is not that much money these days.

Now comes the hardest part. Waiting for the members below you to join. This requires patience. They now need to wait for their downline to grow. You should try to help the members below you by answering their questions and easing their mind. If you did it, they can do it!

A couple of days will pass again. You begin to think that you were fooled and then suddenly... Pop! look into your mailbox. Excited you open it...$2 x 5=$10! in your PayPal account. You are stunned! Although the sum isn't big, you scream out loud because your initial investment is almost paid back. It worked! It really worked!

Quickly you telling others about Contagious Plan. Excitedly you write in the message board that you have got your first payment! "It really works, so now I'm going to join again!"

A couple of days later...Pop! ...$120! Gosh! Two weeks later...$200! "Sheezzaam! This really works! How could I ever doubt in this?!"

You can continue to go it alone and do all the hard work, invest all the time and money it takes to build a downline of eager opportunity seekers who also want to make an extra income OR you can at least check it out.

http://www.contagiousplan.net/club10/mspitler.htm

4. Why do I need you? Can't I join the MLM company directly?

Of course you can join any business opportunity you want without our assistance. If you are willing to continuously work countless hours convincing others to join under you to keep your downline filled. You will almost certainly fail and lose confidence in the network marketing method.

Contagious Plan helps you with the hardest part of MLM...to sponsor people. When everyone who joins does just a little marketing everyday, everyone's downline stays filled! Everyone earns doing just a fraction of the work that the super salespeople have to do!

Each of us wanted to earn some extra income when we tried out our first MLM company. Because we were working alone we failed. That's why we started the club! We knew there had to be a better way. What if the 95% who would normally fail joined together to help each other SUCCEED?! Contagious Plan was born with this thought! We want to help YOU make money!

6. What if the company closes after 6 months? I don't believe any MLM company!

Normally, MLM companies fail when the growth stops and the revenue generated is far less than the Multi-Tier Payouts. Contagious Plan does not have any Payouts each member pays his upline directly, so there is no question of closing. We take only a part of your fee to keep the Website going and to cover the administration cost.

If you have done the little work needed to train your immediate downline to do what you did, you can watch as the members below you join and pay as well. Then you will start receiving $$$ from your downline!

If you choose to do nothing it will take a lot longer to fill your downline. But hey, you did nothing, so why complain? You never have to do anything except for paying the fee when invited to join under your upline member.

7. This looks like a pyramid scheme to me. How can you say it is legal?

Pyramid schemes or chain letters are illegal. Contagious Plan is NOT one of those. Contagious Plan is a Downline building Club. We help you build downlines with interested people who want to join the MLM companies.

In a pyramid scheme you buy yourself a position in a network in order to make money and the company offers no product. The way you make money is to get other people to join under you and get them to get others to join under them, without getting a product.

Dougal Sutherland · Jul 11, 2005

Yeah, it's real. See
http://www.math.sunysb.edu/~dougal/phpBB2/viewtopic.php?t=20

If you want to do it, though, there's an easier way than just looking
around haphazardly for your 5 referrals--use a conga line. The idea
behind a conga line is that you sign up under the top person. When he
gets his 5 referrals, he moves off the list, and the next person is up.
When you sign up, you go to the bottom of the list. That way, it's more
organized, and thus both faster and easier than just looking for
friends to do it (of course, you can get friends to sing up straight
under you, rather than joining the conga line, speeding it up slightly
for those you can get).

A good conga line to join is http://freeipods.co.nr. It's small, but
growing fast -- meaning you'll get your iPod quicker than on those huge
congas.

You can't really put two AC supplies in parallel because if they get
out of phase they'll start eating each other's power as fast as they
possibly can and will blow up

Are you sure you're right, here? After all, the National Grid is supplied by
no end of alternators all in parallel. Once an alternator has been put on
line it remains in phase automatically because it can't do anything else.
It's getting it on in the first place that's the trick (but not a big one).
Lamps across each pair of phases will go out when the phases are in phase,
so to speak, and the alternators can then be switched together.

Hi,
That makes sense in big national generators. As you say, the problem
is *getting* the generators in phase to start with, and making sure
they don't drift out. Alignment circuitry and things are a tiny
fraction of huge national-power-grid generators, but I'm guessing
they're a larger percentage of the components in a little homebuilt
system (and I'm assuming SS is not asking how to build a national
electrical grid on alt.electronics - you never know though <G&gt

.
Still, on second thought, it probably shouldn't be too complex even
for a personal project; assuming you get both generators running at
the same *speed*, then *phase* matching is probably pretty easy.

I always missed the ability to have a video out- to display data on a

Ron,

I saw this product in the September issue of Nuts and Volts. Its a
very nice product for the price and the color video is a must. I
checked out their Pong game application and the color and graphic
charatcers are a nice touch but it has so many more applications. I'm
gonna pick one up. So far their customer testimonials sound good. I
found it www.multilabs.net and the Pong stuff is on the Applications

Are you sure you are right? Run an amplifier in bridge mode and you
basically have 2 electonic generators connected in antiphase and you will
get lots of power without one side trying to catch up with the other.

I always thought that the national grid machines synced up because a
generator can also act as a motor and any out of phaseness with the grid
means the grid will drive the generator till it goes back in phase.

[snip]

Hi,
Yes, that's true, BUT: a bridge amplifier uses two antiphase supplies,
one on each side of the load circuit. The output voltage will be
twice the output voltage of one of the "half-amplifiers". The
original poster asked about outputting 110V from two 110V supplies,
so I assume (s)he wanted the supplies to be in parallel (i.e. grounds
both on one side of the load, hots both on the other side). This is
basically like taking an amplifier in bridge mode and connecting a
zero ohm "speaker" to it.

You'd better be in phase!

Hi,
I couldn't and still can't find the original post, but we seem to agree with
each other in that they absolutely have to be in phase.
My point was also that machines connected to the grid will not behave like
the above situation and will lock automatically, so long as they don't
explode first.

Are you sure you are right? Run an amplifier in bridge mode and you

other.

Hi,
Yes, that's true, BUT: a bridge amplifier uses two antiphase supplies,
one on each side of the load circuit. The output voltage will be
twice the output voltage of one of the "half-amplifiers". The
original poster asked about outputting 110V from two 110V supplies,
so I assume (s)he wanted the supplies to be in parallel (i.e. grounds
both on one side of the load, hots both on the other side). This is
basically like taking an amplifier in bridge mode and connecting a
zero ohm "speaker" to it. You'd better be in phase!

The largest chargeable battery I have seen in a "D" cell was a rating of
4,000 mAh. This would be 4 Ah. This battery type was an industrial rated
battery primarily for running portable lighting equipment, and
communications equipment. The standard "D" cells that I see are rated at
2,000 mAh. Maybe the battery you saw is really rated at 1,100 mAh, and
they made a printing error?

Take note that most of these chargeable batteries are rated at 1.25 to
1.35 Volts. They are not usually rated at 1.5 Volts. If you are building
a pack to run 12 Volt equipment it would be best to use 10 of these
battery types in series. We have also built packs with 16 of these
batteries in series and put an efficient high current capacity voltage
regulator on its output to regulate the output voltage down to 12.5
Volts. Some customers asked for 13.8 Volts to be equivalent to the same
voltage that can come from the average automobile.

If you want to have more current, you can make up combinations of series
and parallel configurations with these batteries. If we put three sets
in parallel in order to have three times the current capacity. When this
is done, then portability becomes another issue.

The rating of 11,000 mAh for a single "D" cell sounds very high, or this
is battery type I have not seen yet!

Questions.

1. I've found online a NiMH D-Cell boasting 11,000 mAh for $9. Can that
be
true?

2. The few Li-ion in D-Cell config I've found have pathetic milli amp
hours.
Are there any that will last a long time in something like, oh, a baby
swing
and/or flashlite?

3. I know that the unused shelf-life of NiMH and cads are pretty bad.
But
what of the lithiums? This is important because I'm interested in
flashlight usages too.

Are there any good pointers to D-Cell rechargables (not the old zincs or
lead-acid's)?

Inteded uses:

Baby swing
Flashlights
Radio

4. I know that a regular D-cell (and others) are 1.5 V. Is there a
"under
load" consideration that changes specifications for that? What are the
amps
of such things. I understand the concepts of volts, amps, amphours,
etc.,
but do not understand them as they relate to batteries. Furthermore
I've
read that the rechargables typically don't quite reach the 1.5 voltage.

Thanks!

I haven't seen any 11,000 mAh NiMh batteries, but I have seen
8,000 mAh 'D' cells for 9 or 10 dollars.

A standard 'D' alkaline cell will be about 16,000 mAh and
has a long shelf life. Alkalines are probably better for
the radio if you don't play it all day long. Same goes
for the flashlight if you don't use it much.

I hear recharable Lithium cells have a very long shelf life
(charged) but they may blow up if overcharged. I think the
capacity is about the same as ni-cads.

Live and learn! I have never seen a "D" battery at 11,000 mAh.

The largest that the suppliers I deal with can supply is at 4,000 mAh.

A high density 'D' ni-cad is 4000 mAh, but a high density NiMh is
8000 mAh. 4000 mAh NiMh 'D cells are actually a samller 'C' cell
inside a 'D' package. Lots of air inside.

I know this sounds too good to be true. But this is the real deal!
They've even reported on it in wired magazine and CNN Headline News!
This really is legit. My friend just got his ipod in the mail! This is
not an ad, I'm just trying to get my free ipod!

It's easy to do!

1>just follow the link (cut and paste address into browser):

http://www.pvps4free.com/default.aspx?r=42103

2>Sign up (choose your free gift: ipod color, Archos AV420, iRiver
PMP-120, Creative Zen PMC or $450 cash!)

3>Participate in one online offer. (they are mostly trial offers that
can be canceled after the trial period (like aol/netflix trial
memberships).

4>Refer some friends.

5>once they sign up and complete one offer....

YOU GET YOUR FREE IPOD COLOR!!!

About the ipod color:
A delight for the ears. A feast for the eyes. Though it's no bigger
than a pack of playing cards and weighs in at just over 6 ounces, iPod
Photo delivers a one-two sensory punch. Letting you carry an entire
library of your favorite music - up to 15,000 songs - or enough photos
- as many as 25,000 - to fill nearly 200 slide trays or cover nearly
5,000 square feet of wall space. Got a really big den? You can even
hook it up to your TV or STEREO!!

For most apps the best dimmer is a switchbank, one switch per light

dimmer apps but has considerable advantages where it is appropriate.
