lurking
lurk
lurker

   <messaging, jargon> The activity of one of the "silent
   majority" in a electronic forum such as {Usenet}; posting
   occasionally or not at all but reading the group's postings
   regularly.  This term is not pejorative and indeed is casually
   used reflexively: "Oh, I'm just lurking".  Often used in "the
   lurkers", the hypothetical audience for the group's
   {flamage}-emitting regulars.

   Lurking and reading the {FAQ} are recommended {netiquette} for
   beginners who need to learn the history and practises of the
   group before posting.
