All characters, except guests, can build things in MOOville. They are not associated with accounts on the Writing project system. Students can navigate the space of MOOville and can interact with objects. TAs and faculty are full MOO programmers with 100,000 quota. They can create new rooms, objects, and realms.
Wizards are system administrators.
They make changes to the entire system. They can access anyone's work and they can remove any user from the database.
