2.1.  Definitions

   An "article" is the unit of news, synonymous with an [RFC 2822]
   "message".  A "proto-article" (7.2.1) is one that has been created by
   a "posting agent" but has not yet been injected into a Netnews system
   system by an "injecting agent". It may lack some otherwise mandatory
   headers.

   A "message identifier" (F-3.1.3) is a unique identifier for an
   article, usually supplied by the posting agent which posted it or,
   failing that, by the injecting agent. It distinguishes the article
   from every other article ever posted anywhere. Articles with the same
   message identifier are treated as if they are the same article
   regardless of any differences in the body or headers.

   A "newsgroup" is a single news forum, a logical bulletin board,
   having a name and nominally intended for articles on a specific
   topic. An article is "posted to" a single newsgroup or several
   newsgroups. When an article is posted to more than one newsgroup, it
   is said to be "crossposted"; note that this differs from posting the
   same text as part of each of several articles, one per newsgroup.

   A newsgroup may be "moderated", in which case submissions are not
   posted directly, but mailed to a "moderator" for consideration and
   possible posting.  Moderators are typically human but may be
   implemented partially or entirely in software.

   A "hierarchy" is the set of all newsgroups whose names share a first
   component (as defined in F-3.1.5).  The term "sub-hierarchy" is also
   used where several initial components are shared.

   A "poster" is the person or software that composes a possibly
   compliant article for submission to a posting agent. The poster is
   synonymous with [RFC 2822]'s author.

   A "reader" is the person or software reading news articles.

[Alternative-1.]

   A "followup" is an article containing a response to the contents of
   an earlier article.

   An article is a "precursor" of some later article which is a followup
   to it, or which is otherwise intended to be grouped with it for
   purposes of display (e.g. as a part of a multipart posting such as a
   FAQ).

[Alternative-2.]

   A "followup" to an earlier article (its "precursor") is one intended
   to be grouped with that article for purposes of display (e.g. because
   it is a response to its contents or is a part of a multipart posting
   such as a FAQ).
[End of alternatives]

   An (email) "address" is the mailbox [RFC 2822] (or more particularly
   the addr-spec within that mailbox) which directs the delivery of an
   email to its intended recipient, who is said to "own" that address.

   A "sender" is the person or software (usually, but not always, the
   same as the poster) responsible for the operation of the posting
   agent or, which amounts to the same thing, for passing the article to
   the injecting agent.
[Is the definition in RFC 2822 sufficient?]

   A "control message" is an article which is marked as containing
   control information; a "serving agent" (and in some cases a "relaying
   agent") receiving such an article may (subject to the policies
   observed at that site) take actions beyond just filing and passing on
   the article.
