Hi guys. I would like to know if this concept exists (I think I heard of it some months ago) and if it does, then where can I find this site or information? I want to know if there are membership sites (for sale) already made and ready to just install and profit? It is something like ready made Adsense sites but with Membership sites. If you know of some service or site like that, I really appreciate you to point me in the right direction. Thanks.!
