Mainstream software like NATS?
 

Are there any mainstream products worth checking out for managing memberships and affiliates?

Thanks!

here we have a list of all program shells i spotted among 1,5k programs: http://www.signbucksdaily.com/search/index/

sorry, no recommendations, just a list. you may get all programs under that shell right there

Well. if your site is using membership and affiliates traffic model, adult or mainstream, NATS can do the job imho

This link is very helpful, thanks!
