This would seem like your typical DikuMUD.  It started with
classes, and 30 to 50 levels, and in fact, a silly and
modified version of that is currently up -- a very
interesting class system, and challenging, oldschool
style. Essentially we have an archive of over 27 years
of versions of this mud-all which are radically
different from each other. This particular version, as
stated above, consists of your typical dikumud areas,
along with some interesting higher level areas, and
several attempts at humor hidden within these
areas, and equipment within, added throughout the
years.  It truly is fun, andthere usually is someone
on willing to help newbies.  If you've ever played a
traditional circlemud or dikumud, you'll be able to 
figure this out while enjoying it.  And remember -- 
this is the longest running DikuMUD EVER. There's a
reason for that: it was always at either
judy.indstate.edu 2150, henry.indstate.edu,
fred.indstate.edu, laurel, and ramsey.indstate.edu,
and now it is on laurel.indstate.edu 2150, so
unfortunately we've lost a lost of players.
However you're welcome to come! There is always
someone on wanting to give you the secrets of the
game, and help you out! This post was put up in the
hopes that the old players will have the opportunity
to find these versions, should they try to search,
but ultimately, everyone is welcome! Cheers!
