post
posting
A message sent to a newsgroup or mailing list (may also be called "a post") or the act of sending it. Distinguished from a "letter" or ordinary electronic mail 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 e-mail; perhaps the best dividing line is that if you don't know the names of all the potential recipients, it is a posting.
