BuddyPress.org

It’s crudely possible by just setting ‘only user accounts can be created’ in site > options. Then everyone is a ‘subscriber’. mu doesn’t have a variable setting for default user roles. subscribers can only comment on posts. Gonna hafta manually change them to something else.

for a discussion on this topic.

I wanna do something similar. I want to create a blog for each group at group creation time (optionally). All group members to have author/contributor roles.

Groups are the most important component in bp for me. Groups should have a wire, forum, and blog. And a bowling league. Bowling leagues are important too.
