Re: How does buddypress.org organize forums?
This site uses “Deep integration” with a standalone bbPress install. In the near future, this website will change and forums/groups will follow the regular BuddyPress model. The only reason this is like it is currently is because of historical reasons and the fact that the site’s theme hasn’t been updated for a long time.
If you want a site wide forum, just create a group and call it “site wide discussion”. Easy as that.
