What is a MOO?

A MOO is a MUD Object Oriented and a MUD is a Multiple User Domain (or Dimension, or Dungeon).
MUDs are descendents of the original Adventure and Zork games, but enhanced to allow multiple players. The domain provided a space to explore or conquer, but there is also the unpredictable interaction with other players, that no no single user game could have. MUDs and MOOs are hosted on a server and then multiple users connect.
MOOs took this one step farther, by allowing certain classes of users(programmers and wizards) to extend the domain, by adding new rooms and objects. There are social MOOs, game MOOs and educational MOOs. The MOO is customizable to provide unlimited types of experiences.
This particular MOO is an educational one, so very few people have the ability to enlarge the museum.
