Hey Develish!
AVS sites are not good anymore, at least not the free model... users are aware of the trick and they dont bite it anymore as in the past.

Also AVSs are supposed to be illegal, they are not supposed to be able to do that anymore nowadays...

if you want to go with a recurring program that maintains your members i suggest checking the AENs out there, for instance start by checking www.prideaccess.com

and if you need anything just hit me up on icq and i will gladly give you a hand!
cheers.
Thy
