Midbie--More established than a typical lowbie, but not as awe-
inspiringly powerful as a highbie. Midbies are the middle of the
road. Some have no reason to attain extremely high levels just yet,
but most are well-established, with some kind of stake in the MUD
-- either close-knit relationships with fellow mudders (who may or
may not be midbies) or property and relatively cool equipment.

You may immediately shoot up into midbie-dom if you had an
illustrious career as a newbie and lowbie, or maybe not -- it
depends on what you did. Depending on your temperament, being a
midbie may be the best thing to be, or the worst.
