Affiliate Program
 

I've been running photopost classifieds for about 2 years now. I have been thinking of adding an affiliate program to my website so that others can send traffic and if that traffic results in a paypal sale, then I can give commissions.

Does anyone know a good affiliate program software that would work well with photopost classifieds and paypal?

Has anyone ever done this before and would this possibly be a future add on to the software?
