cross-post

[Usenet] 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 only one part of the original posting.
