            The NNSC provides information services and technical  assis-
            tance  to  NSFNET  end-users.   Information  and  documents,
            available in online and/or printed form, cover  topics  such
            as  resources  (Internet  Resource  Guide),  contacts at the
            mid-level networks and at local campuses  and  institutions,
            and  network  status  reports.   When prospective or current
            users do not know whom to call  concerning  their  questions
            about NSFNET use, they should contact the NNSC.

            Online information is available  from  the  Info-Server,  an
            automated program which distributes documents in response to
            specially formatted messages.  For  instructions  about  the
            Info-Server, send a message to info-server@nnsc.nsf.net with
            ``HELP'' in the body of the message.

            ring questions to a more appropriate source for information,
            to  users  with  general Internet-related questions or prob-
