Personally, I have tried GammaCash, albiet not for a very long period of time and I didn't do very well with the partnership program. I am going to give them another try using the signup program. My best recurring sponsor is
PornMegaBucks The best feature of there program is that when the surfer signs up for 1 site, they get access to all the other 20+ sites, AND you can advertise this! I also just joined
TopBucks but I'm using the per signup program...
