Aren't you lucky! LISTSERV(R) version 1.8c introduces the concept of
super-lists (a list that contains other lists). You create your super
-list and use the "Sub-lists=" keyword to tell it what all the
sub-lists are. If you send a message to the super-list, everybody who
is subscribed to at least one of the sub-lists with MAIL set will get
one and only one copy of the message (no matter how many of the lists
that address is subscribed to).
