It is _possible_, but quite inconvenient (and not very dynamic,

The way it currently can be done, is by adding _all_ member addresses
on the master list and the sub-lists to the "posters" text box in the
"Privacy Options" page of the master list.

This means that you'll have to update the "posters" text box whenever
some of the sub-lists (or the master list) changes, though.

This is easier -- you want the "member_posting_only" setting set to
"yes" on this "expanded" master list.
