webmaster
     
         (Sometimes "webmistress") The alias or role
        of the person(s) responsible for the development and
        maintenance of one or more {web servers} and/or some or all of
        the {web pages} at a {web site}.  The term does not imply any
        particular level of skill or mastery (see "{webmonkey}").
     
        The webmaster's {e-mail address} often appears on the {home
        page} of the site.  Failing that, you could try sending e-mail
        to {postmaster} (from which the term is probably derived) or
        {root} at that {host}, possibly after removing an initial
        "www.".
