BuddyPress.org

Does anyone know if Buddypress have a way to charge members to use and create buddypress groups? What I want to do is for people to sign up to my site (Im assuming via Buddypress to keep things simple) and have the first 50 members sign up for free. Then afetr I have that, is there a way to charge members? Im just not sure how this stuff works.

Thanks if anyone can help.

Kris.
