As the link I sent explains, many groups are read by the same people, so
you're likely to get an answer by posting in only the most appropriate

If you really don't know what group is most germane, then cross-posting
(putting two groups in the To: header) will allow the post to show up in
both groups, and both groups will see any replies.
