posting

( n.)

   Noun  corresp.  to  v.:  {post} (but note that {post} can be nouned).
   Distinguished from a `letter' or ordinary {email} message by the fact
   that  it  is  broadcast  rather  than point-to-point. It is not clear
   whether  messages sent to a small mailing list are postings or email;
   perhaps the best dividing line is that if you don't know the names of
   all the potential recipients, it is a posting.
