From time to time it is necessary to remove a conversation from
a particular newsgroup for one reason or another. Two of the
most common reasons are that discussions are not permitted in
the newsgroup which the posting originated in and another is
that the topic of discussion has strayed from the original
sufficiently to warrant a change in newsgroups.
Misc.jobs.offered and misc.jobs.resumes are for the posting of
job offers and resumes only. This means that all postings
should include a Followup-To: line. This can be done by adding
to the article header. The rn newsreader provides an empty
space which you can use to put the appropriate groups in.
Other newsreaders do not and you should add one by hand.
This line should be added after the Newsgroups: line.
