Doesn't seem long winded but okay?
[sub]I think that those under the invite list of groups that require approval who are still listed as invite can view chats. I mean chats for groups that you can only view if you are a member. If that is true then other users could be put in bad positions if there are things in those groups that shouldn't get out to the public and can be used against them. Gonna try nd run some tests to confirm it though.[/sub]
