I think there should be private forums for users in certain usergroups. Moderators could have their private board, that global mods and admins can access too, global mod would also have a private board, admins can also access it, and if we will ever have 2 or more admins, admins could also have their boards. In the boards, the mods/global mods/admins would talk about various (important) stuff for the forum. Also, since global mods could access the mod forum and admins could access both the global mods and mods forum, admins would have to talk about the forum moderation in these board only. Sorry if it was badly explained, I'm not the best at explaining this kind of stuff.
EDIT: ALSO RANKS. AND RULES.
