I’m also looking for this. Looks like one option is User Account Type Pro (http://rimonhabib.com/buddypress-user-account-type-pro-has-been-released/) but the information on this is sketchy, the pro site page is currently in maintenance mode and I read on another post that it is not compatible with 1.8. Also the Lite version on the WP repo has a few unanswered questions about whether this is being supported.
So that looks a bit bleak. Anyone have any other ideas?
