BuddyPress.org

Burt Adsit developed a plugin called “Community Blogs for BuddyPress”. The cool thing is that it adds users silently to the set blog by the admin.

I will look at his approach and see if it is at all possible to have moderators of the group added silently as well. And maybe members at a different level.

So an group admin would be the blog admin. Group moderators would be editors and group members, authors.

Probably an additional menu should be available to select what role group members get assigned. I thought about this as well, so good feature request
