BuddyPress.org

@jakel I did ask the developer about being able to fill in the registration form, but his response was “only autoregistration is supported. It’s on my to-do list for eventual implementation, no time estimate yet though.”

I’m sure it’s possible, although I know I don’t have the skills to do it.

@r-a-y in response to your edit, currently when a new user is added with the fb plugin they don’t appear as a new user in the activity stream, would this also be solved by using bp_core_activated_user ?
