A guest on the system, especially one who generally logs in over a
network from a remote location for {comm mode}, email, games, and other
trivial purposes. One step below {luser}. ITS hackers often used to spell
this {turist}, perhaps by some sort of tenuous analogy with {luser} (this
usage may also have expressed the ITS culture's penchant for
six-letterisms, and/or been some sort of tribute to Alan Turing). Compare
{twink}, {lurker}, {read-only user}.
