As far as I can tell, you can create a superlist that contains as sublists 2
or more lists that already exist on your server. But what do you have to do
if you want to sublists WITHIN an existing list. For example, I own
MYLIST-L. I'd like to have a sublist, perhaps called MYSUBLIST-L, that can
be used by a subset of the current subscribers to MYLIST-L. Do I have to go
thru the normal process of getting a new list created on my institution's
server, & then make it a sublist of MYLIST-L? Or is there a way I can create
the sublist from with MYLIST-L. What will happen if I set MYLIST-L's
"Sub-list" keyword to "Sub-lists=MYSUBLIST-L?"

Thanks,
Pat
