        !            31: USENET (Users' Network)
        !            32: is a bulletin board shared among many
        !            33: computer systems around the world.
        !            34: USENET is a logical network,
        !            35: sitting on top of several physical networks,
        !            36: among them
        !            37: .i UUCP ,

        !            40: .i X.25 ,
        !            41: and the
        !            42: .i ARPANET .
        !            43: Sites on USENET include many universities,
        !            44: private companies and research organizations.
        !            45: Most of the members of USENET are either
        !            46: university computer science departments
        !            47: or part of AT&T.
        !            48: Currently, there are over 2000 USENET sites in the USA, Canada, Europe, Japan 
        !            49: and Korea with more joining every day. Most are running the
        !            50: .ux
        !            51: operating system.
        !            52: .pg
        !            53: The network news,
        !            54: or simply
        !            55: .i netnews ,
        !            56: is the set of programs that provide access to the news
        !            57: and transfer it from one machine to the next.
        !            58: Netnews was originally written at Duke University
        !            59: and has been modified extensively by the University
        !            60: of California at Berkeley and others.
        !            61: Netnews allows articles to be posted for limited or very wide distribution.
        !            62: This document contains a list of newsgroups
        !            63: that were active at the time the document was written.
        !            64: It exists
        !            65: to assist you in determining which newsgroups you may
        !            66: want to subscribe to.
        !            67: When creating a new article,
        !            68: the level of distribution can be controlled
        !            69: by use of the
        !            70: .cf Distribution
        !            71: field.
        !            72: This will prevent notices of apartments for rent in New Jersey
        !            73: being broadcast to California
        !            74: (or even Europe).
        !            75: .pg
        !            76: Any user can post an article,
        !            77: which will be sent out to the network
        !            78: to be read by persons interested in that topic.
        !            79: You can specify which topics are of interest to you by putting them in a
        !            80: .i "subscription list" .
        !            81: Then,
        !            82: whenever you ask to read news,
        !            83: the news reading program will present all unread articles of interest.
        !            84: There are also facilities for browsing through old news,
        !            85: posting follow-up articles,
        !            86: and sending direct electronic mail replies to the author of an article.
        !            87: .pg
        !            88: This paper is a tutorial,
        !            89: aimed at the user who wants to read and possibly post news.
        !            90: The system administrator who must install the software
        !            91: should see the companion document
        !            92: .i "USENET Version B Installation" .
        !            93: .hu
        !            94: Why USENET?
        !            95: .pg
        !            96: USENET is useful in a number of ways.
        !            97: Someone wishing to announce a new program or product can reach a wide audience.
        !            98: A user can ask \*(lqDoes anyone have an
        !            99: .i x ?\*(rq
        !           100: and will usually get several responses within a day or two.
        !           101: Bug reports and their fixes can be made quickly available
        !           102: without the usual overhead of sending out mass mailings.
        !           103: Discussions involving many people at different locations
        !           104: can take place without having to get everyone together.
        !           105: .pg
        !           106: Another facility with similar capabilities to
        !           107: .i netnews
        !           108: is the
        !           109: .i "electronic mailing list" .
        !           110: A mailing list is a collection of electronic mailing addresses of users
        !           111: who are interested in a particular topic.
        !           112: By sending electronic mail to the list,
        !           113: all users on the list receive a copy of the article.
        !           114: While the mailing list facility is quite useful,
        !           115: USENET offers a number of advantages not present in mailing lists.
        !           116: Getting yourself on a mailing list is not always easy.
        !           117: You have to figure out who maintains the list and ask them to put you on it.
        !           118: Often these people are out of town or busy,
        !           119: and don't put you on the list for several days.
        !           120: Sometimes you have to send mail to the entire mailing list,
        !           121: hoping that one of the readers will tell you who maintains the list.
        !           122: Once you are on the list,
        !           123: you often find yourself in the middle of a discussion.
        !           124: Netnews keeps old articles around until they expire (usually about two weeks)
        !           125: so you can browse through old news to catch up on what you missed.
        !           126: Similarly,
        !           127: referring to an old article is easy,
        !           128: without having to keep a personal file of all old mail to the list.
        !           129: .pg
        !           130: Another advantage is appreciated by the other users of the system.
        !           131: There is less overhead in having only one copy of each message
        !           132: sent to each machine,
        !           133: rather than having separate copies sent
        !           134: to each of several users on the same machine.
        !           135: This cuts down on computer time to process the messages,
        !           136: and on-line costs for telephone calls to transfer messages
        !           137: from one machine to another (when phone lines are used).
        !           138: Another advantage is in the disk space consumed.
        !           139: When only one message is sent to each system,
        !           140: only one copy of the message is kept on disk.
        !           141: In a mailing list environment,
        !           142: each user has a copy in a mailbox.
        !           143: .hu
        !           144: How do I Read News?
        !           145: .pg
        !           146: In the USENET jargon,
        !           147: interest topics are called
        !           148: .i newsgroups .
        !           149: A newsgroup list appears in a later section,
        !           150: current as this paper was written.
        !           151: You have your own
        !           152: .i "subscription list"
        !           153: of newsgroups to which you are said to
        !           154: .i subscribe .
        !           155: .pg
        !           156: The simplest way to read news is to type the command:
        !           157: .sd c
        !           158: readnews
        !           159: .ed
        !           160: Other possibilities include: a full-screen-oriented news reading program,
        !           161: .i vnews (1),
        !           162: (described in the Appendix) and the
        !           163: .i notesfile
        !           164: system, which can also be used for news (described in a separate paper.)
        !           165: Each newsgroup to which you subscribe will be presented,
        !           166: one article at a time.
        !           167: As each article is presented,
        !           168: you will be shown the
        !           169: .i header
        !           170: (containing the name of the author,
        !           171: the subject,
        !           172: and the length of the article)
        !           173: and you will be asked if you want more.
        !           174: There are a number of possible choices you can make at this point.
        !           175: The three most common

        !           200: for \*(lqno\*(rq.

        !           203: A third option is

        !           224: .pg
        !           225: If you are reading news for the first time,
        !           226: you may find yourself swamped by the volume of unread news,
