it means technically that Mudcat has not set a cookie to allow a person to be 'recognized' when they sign on...there are certain things therefore they can't access...like private messages. Max & Jeff just named this 'guest' when they created the special services a few years ago.

Some do this for a reason, some because than can't set cookies at work...etc...

some simply refuse to be identified in ANY way, even by an anonymous name.
