   message heading or body, including:
   + user email address

   + current date

4. Administrator can create a query which generates a list of
   addresses.  The query can be given an identifying name, stored,
   edited, and used at a later date.  When the query is used, it
   generates a list of matches at the time it is used, not the time it
   is created.  The query can include these match fields:
   + List of topics users have opted in to

   message.
