Hmmm. I don't know what happened, Mark. I didn't get a copy so I can't
see it. The copy saved (via IMAP) to my mail server looked OK, so the
problem may have been with the SMTP transfer. I'll try again. I just
copied and pasted the URLs from my browser location widget, but the
long URL may have confused my MUA and caused the problem. I didn't see
the TinyURL URL. Sorry!!

The configuration will be:

Master List ("umbrella list") - linked to siblings via regular_include_lists:
	sibling list 1
	sibling list 2
	etc.

Posts to the Master List will deliver _one_ copy only to each of the
subscribers on the several sibling lists, regardless of CCs or
duplicate addresses across these lists. I believe this is a feature of
regular_include_lists.

I understand that unsubscribe instructions on posts distributed via
(addressed to) the Master List will be relevant to the Master List,
although the address to be "unsubscribed" may exist on one or more
sibling lists. Since at least one of the sibling lists will contain the
email addresses of dues-paying members, it's necessary that the
unsubscribe request be processed on the Master List as an instruction
to _not_ distribute to the unsubscribing address rather than as an
instruction to unsubscribe the address from any or all sibling lists.

Disablement or removal of addresses due to bounces, on the other hand,
should propagate to all sibling lists and cause them to be disabled or
expunged in every list on which they occur.

I hope this is clear this time :)

Can Mailman do these things?
