[Mailman-Users] closely related lists - using users from a different lists

[David Cake]

	I have two lists that are effectively low and high traffic 
lists designed to serve the same constituency. So that a large number 
of people do not need to be subscribed to announcements that go out 
on the low traffic list, the high traffic list is also subscribed to 
the low traffic list.
	The only problem is that this means almost no one is 
subscribed to the low traffic list, and virtually none of the people 
who might post to it are, so almost every message is moderated.
	Is there a way to allow people who are subscribed to a second 
list to be accepted as subscribers to the first?
	Cheers
