Went into the plugin code and found the lines relevant to auto joining (lines 29-30 of bp-forums-screens.php and I don’t see anything regarding BP_DISABLE_AUTO_GROUP_JOIN so I’m guessing it was removed some time in the last 11 months. I commented out those two lines and my test users no longer auto join when posting new topics or replying. I realize I may have to redo this if BuddyPress gets updated in the future…
I’ve done some more testing and it looks like the super admin for the blog can post to groups without becoming a member but no one else can. As soon as I use a test account to post to a forum that account gets auto added to the group.
It seems like a major assumption on BuddyPress’ part that people will always want to auto join groups….why didn’t they even think to make this an option?
@tommyhoang what did you do to get this working? I’ve got bp-custom.php in place but it doesn’t seem to be doing anything. I just created the file using my ftp client. Is there a particular way I need to add the file in order for BuddyPress to recognize it?
