Could you please share your setup of the private forums?

At the moment this is our setup, but we are thinking about changing it a bit.

>> Category : Site Administration
>>>> Forum : Test Forum (use this for testing articles, markup, etc)
>>>> Forum : Moderators Lounge (super mod-, mod-, and admin- only chats)
>>>> Forum : Admins Lounge (administrator only chats)
>>>> Forum : Tash Bin (the history of our board)

Mine is fairly straight forward:

VI Management
-- Forum Management (staff forum)
-- IRC Management (forum for irc channel ops and halfops)
-- The Trash (archive forum for rule violating posts)
