I think I’m going to have to use the Group Forums, but I can’t figure out how to turn off the site-wide forums.

Go to wp-admin dashboard menu BuddyPress > Forums and deactivate sitewide forums.
Then to Plugins > Installed Plugins, deactivate then delete bbPress plugin.
Also remove the Page generated for sitewide forums, if any, in Pages > All Pages. That would go to trash. Go to trash and delete that page permanently.

Okay. That’s great. I got rid of it. Thanks. The next thing I need to do is just get people to automatically join a group when they are registered, so they don’t have to create a group to post.
