also, a MOO player class that has all the capabilities of a programmer but operates outside the permission system.

Wizards can recycle objects at will, toad and newt players, put a room within a room within a room within their pocket ... they can do everything that does not violate the MOO server consistency rules (which means that they cannot , e.g. put something into itself or make an object the child of its children).

Other duties/powers of the wizards include shutting down the MOO, forcing a database dump, blacklisting abusive sites ...
Every MOO comes with a pre-made wizard, object #2.

Sociologically speaking, wizards are the mothers and fathers of the MOO, and players in general will come crying to them for just about everything.
This keeps happening until some attempt at social reform is done - usually with mixed success, witness LambdaMOO.
