Where can I learn about the php link biding directory

[HellMind]

I need some help about the billing system,
Its a bid that overtime rest an amount of cash?
How can be configured?

[David]

Can rephrase the question?
I don't quite understand this:
Its a bid that overtime rest an amount of cash?

You charge X dollars for a featured link.
You set the miniumum it can be increased at a time.

People then pay X to stay on top.
You get it right you can make some money.
You get it wrong by tossing it up on a dropped domain with PR that will drop and spend no time developing it....
you will make nothing.

Then what for is the subscription option?
I want to make it more dynamic
To force the ppl to pay every month or something like that
