tourist
     
         A guest on the system, especially one who generally
        logs in over a network from a remote location for {comm mode},
        {electronic mail}, {games} and other trivial purposes.  A
        tourist is one step below a {luser}.
     
        Hackers often spell this {turist}, perhaps by some sort of
        tenuous analogy with {luser} (this also expresses the {ITS}
        culture's penchant for six-letterisms).
     
        Compare {twink}, {read-only user}.
