Unless I'm missing something.
Currently, users first register for the Protected Content membership. Then after the paypal purchase (subscription), they're redirected to their account page, which has no mention of buddypress or access to the menu bar to update/edit their buddypress profile. It seems they then have to register again, using the buddypress register page ".../register-bp/", which would've been granted access.
I switched over from the Membership plugin, which automatically takes over the registration process, combining the two essentially.
Does this function exist with Protected Content? If not, would would be the best way to implement buddypress?
