After you've set everything up, use your mailer to mail a test message
to yourself, and your newsreader or news poster (such as nnpost or
Pnews) to post an article to a test newsgroup (use a local newsgroup
and Distribution set to `local' to save bandwidth).  Note that with
many newsreaders and mailers you will not see your signature while
you are composing a message - it will be automaticlally appended when
you send the message.  Note also that many systems add a line that
contains `-- ' to the top of your sig.  This is used by programs that
automatically deal with mail or news to identify the start of the
signature.

If you have a problem with your sig see the next section 1.4 on
Troubleshooting.
