cross-post

   [Usenet;  very  common]  To  post  a single article simultaneously to
   several   newsgroups.   Distinguished   from   posting   the  article
   repeatedly,  once  to  each  newsgroup, which causes people to see it
   multiple  times  (which  is  very bad form). Gratuitous cross-posting
   without  a  Followup-To line directing responses to a single followup
   group is frowned upon, as it tends to cause {followup} articles to go
   to  inappropriate  newsgroups when people respond to various parts of
   the original posting.
