Just curious what the best method of acheiving this would be?

Right now im considering letting a surfer buy a membership to 1 site and giving them access to 3 others.

My question is this..

Is it possible to give each of our sites more than 1 set of htaccess files so that if a member joins, for example, Tattooed Guys, they can also use the same password on Foreskin Fantasy, Denim Guys and, Ebony Hounds BUT if they join Denim Guys, they wont get access to Tattooed Guys, Foreskin Fantasy and Ebony Hounds?

Does that make sense?

I only want to allow surfers access to 'bonus' sites if they join a specific site.

Anyone know if this is possible to do using CCBill or do i need to give them access to all sites?

Regards,

Lee
