Master Wongery
A Master Wongery is a wiki on the Wongery where editing is not open to the public but restricted to a specific group of individuals. The Central Wongery itself can be considered a Master Wongery with the Grandmaster Wongers are the editors. A Master Wongery can also be called a Private Wongery, although it is only the editing that is private, not the visibility; Master Wongeries are still publicly viewable.
At the time of this writing, there are no Master Wongeries (aside from the Central Wongery), but this may change in the future.
