It comes from years of having to maintain forums with a bit of an iron fist to keep things on track and worthwhile to everyone else. That is why I've tried to make that introductory post very accessible ... to make the process easier to follow and understand.
BTW ... John D's Fantasos is a good affiliate management system.
I'm one of the few fans of PayPal, and wouldn't recommend taking a chance at having your account frozen, but ... you are not actively promoting a multi tier program.
The JV Broker would be the only one bringing in partners on the 2nd tier, and you would be paying them separately ... anyway.
Neither you nor your affiliates would be promoting it as a multi tier program, so I honestly don't see that as a problem.
The 2 tier aspect is never made public ... most certainly during the actual promotion and sale of the product, and is simply a convenient way to keep track.
