         program called "Eudora" for sending and receiving mail.

         b) Listservs.  A listserv is a means to broadcast an email
         message to many users for the purpose of maintaining a
         discussion list.  Although listserv messages are transmitted
         via email, correspondence is public, so extra care should be
         used when participating.  The program called "Eudora" would be
         used for participating in a listserv.

         c) Network News.  Netnews is a communications tool for large
         group discussion.  Netnews is essentially similar to a
         listserv, except that it does not use email as the means of
         communication.  Instead, you use software called a "news
         reader" to read and post messages to the appropriate groups.
         Newsgroups are very public, and should be used thoughtfully.
         The CoVis project employs a program called "NewsWatcher" for
         reading and posting news.

         d) File Transfer Protocol, or FTP.  File Transfer Protocol is a
         means of moving files between computers on the Internet. The
         CoVis project employs a program called "Fetch" for doing this.

         e) Telnet.  Telnet allows you to connect to other computers on
         the Internet, provided you know the machine's Internet address
         and appropriate password.  All provisions of this document
         apply to members of the CoVis community while using remote
         computers via Telnet.  The CoVis Project uses a program called
         "NCSA Telnet" for telnetting operations.

         f) Gopher.  Gopher is a means of navigating the Internet via a
         menu-driven or point-and-click interface to the computer.
         Gopher is a very convenient way to retrieve files and
         information from sources all around the globe. For most
         purposes, it may be considered an easier form of FTP and can be
         used to initiate Telnet sessions.  The CoVis Project uses a
         program called "TurboGopher" for gopher searching.

C.  Who is a member of the CoVis community?

   All account holders on the CoVis Network will be granted access to
   all services the network offers.  The following people may hold
   accounts on the CoVis Network:

      1.  Students.  Students who are currently enrolled in a CoVis
      class will automatically be granted a network account upon
      agreement to the terms stated in this policy;

      2.  Teachers.  Teachers of CoVis classes may hold accounts on the
      CoVis Network.  Other teachers may apply for accounts;

      3.  Scientists.  Scientists who wish to collaborate on student
      projects will be granted CoVis Network accounts.  The exact nature
      of the account (i.e., which services are available) will depend on
      individual circumstances;

      4.  Researchers.  The researchers conducting the CoVis project
      will hold accounts on the CoVis network;

      5.  Others.  Anyone may request a special account on the CoVis
      network.  These requests will be granted on a case-by-case basis,
      depending on need and resource availability.

      Note: Except in special cases listed above, people from the larger
      Internet community are not part of the local CoVis community, and
      will probably be unaware of the existence of this policy.
      However, you should always treat people you "meet" on the network
      with respect, as if they were a part of your community.

D.  Privileges and Rights of CoVis Network Community Members

   Members of the CoVis community have certain network privileges and
   rights.  These include:

      1.  Privacy.  All members of the CoVis community have the right to
      privacy in their email, Cruiser, Timbuktu, and notebook
      communications when so designated by the user. However, if a user
      is believed to be in violation of the guidelines stated in this
      policy, a system administrator or teacher may need to gain access
      to private correspondence or files.  An attempt will be made to
      notify the user of such inspections whenever possible.  As CoVis
      is primarily a research project, researchers may periodically make
      requests to study or view correspondence and files, but
      confidentiality is ensured in such circumstances.  Also, it is
      important that users recognize the fundamental differences between
      public (e.g., news) and private (e.g., email) forms of
      communication, and shape their content accordingly;

      2.  Equal Access.  All members of the CoVis community will be
      granted free and equal access to as many network services as their
      technology allows.  Exploration of the Internet is encouraged
      relative to the purposes of the CoVis Network;

      3.  Safety.  To the greatest extent possible, members of the CoVis
      community will be protected from harassment or unwanted or
      unsolicited contact.  Any community member who receives
      threatening or unwelcome communications should bring them to the
      attention of a system administrator or teacher.  Users must,
      however, be aware that there are many services available on the
      Internet that could potentially be offensive to certain groups of
      users.  The designers of the CoVis Network cannot eliminate access
      to all such services, nor could they even begin to identify them.
      Thus individual users must take responsibility for their own
      actions in navigating the network;

      4.  Intellectual Freedom.  The CoVis Network must be a free and
      open forum for expression, including viewpoints that are strange,
      unorthodox, or unpopular.  The network administrators will place
      no official sanctions upon the expression of personal opinion on
      the network.  However, the poster of an opinion should be aware
      that other community members may be openly critical of such
      opinions.   Occasionally, a message that you post may be met from
      outside the CoVis community with especially harsh criticism (a
      practice known as "flaming").  It is best not to respond to such
      attacks, unless you believe you are capable of a measured,
      rational reply.  Personal attacks are not an acceptable use of the
      CoVis Network at any time. The CoVis Project does not officially

      endorse any opinions stated on the network.  Any statement of
      personal belief is implicitly understood to be representative of
      the author's individual point of view, and not that of the CoVis
      Network, its administrators, or the participating high schools.

E.  Responsibilities of CoVis Network Community Members

   With the rights and privileges of membership in the CoVis Network
   community come certain responsibilities.  Users need to familiarize
   themselves with these responsibilities.  Failure to follow them may
   result in the loss of network privileges.  These responsibilities
   include:

      1.  Using appropriate language.  Profanity or obscenity will not
      be tolerated on the CoVis Network.  All community members should
      use language appropriate for school situations as indicated by
      school codes of conduct;

      2.  Avoiding offensive or inflammatory speech.  Community members
      must respect the rights of others both in the local community and
      in the Internet at large.  Personal attacks are an unacceptable
      use of the network.  If you are the victim of a "flame," take time
      to respond rationally, and bring the incident to the attention of
      a teacher or system administrator;

      3.  Adhering to the rules of copyright.  CoVis community members
      must respect all copyright issues regarding software, information,
      and attributions of authorship.  The unauthorized copying or
      transfer of copyrighted materials may result in the loss of
      network privileges;

      4.  Re-posting personal communications without the original
      author's prior consent is prohibited.  To do this is a violation
      of the author's privacy.  However, all messages posted in a public
      forum such as newsgroups or listservs may be copied in subsequent
      communications, so long as proper attribution is given;

      5.  Use of the network for any illegal activities is prohibited.
      Illegal activities include tampering with computer hardware or
      software, unauthorized entry into computers, or knowledgeable
      vandalism or destruction of computer files. Such activity is
      considered a crime under state and federal law;

      6.  Avoid the knowing or inadvertent spread of computer viruses.
      "Computer viruses" are programs that have been developed as
      pranks, and can destroy valuable programs and data.  To reduce the
      risk of spreading a computer virus, do not import files from
      unknown or disreputable sources.  If you do obtain software or



Manning & Perkins                                              [Page 17]

RFC 1746            Ways to Define User Expectations       December 1994


      files from remote sources, follow proper procedures to check for
      viruses before use. Deliberate attempts to degrade or disrupt
      system performance of the CoVis Network or any other computer
      system or network on the Internet by spreading computer viruses is
      considered criminal activity under state and federal law;

      7.  You have full responsibility for the use of your account.  All
      violations of this policy that can be traced to an individual
      account name will be treated as the sole responsibility of the
      owner of that account.  Under no conditions should you give your
      password to another user;

      8.  Impersonation is not permitted.  Real names must be used,
      pseudonyms are not allowed;

      9.  Anonymity is not allowed on the CoVis Network.  As an
      educational network, we believe that individuals must take
      responsibility for their actions and words;

      10.  Exemplary behavior is expected on 'virtual' field trips. When
      'visiting' locations on the Internet or using the Cruiser or
      Timbuktu communication tools, CoVis community members must conduct
      themselves as representatives of both their respective schools and
      the CoVis community as a whole.  Conduct that is in conflict with
      the responsibilities outlined in this document will be subject to
      loss of network privileges.
