Take a look at http://www.mvps.org/access/forms/frm0028.htm.  That site, by
the way, is just chock-full of useful information.

As the newsgroups are not just for providing free tech support, but for a
learning and teaching experience as well, and with as much malicious code,
viruses, worms, etc., that abounds in the Internet, it may be a bit
difficult to find someone to download and dig out what you are talking
about. It's much more productive to be very specific, copy pertinent code
and detail information into a newsgroup post.

It's also much more productive to summarize the topic of a post in the
Subject, instead of an appeal for help or sympathy.  Many of the people best
qualified to answer may well not have the time and energy to open the post
to determine if it is a subject they can address, or are interested in
addressinng.

It's, finally, also much more productive if you limit a post to one
question... making it easier to summarize in the subject line, too.
