I am a newbie to list servs.

I would like to inform all the list managers and owners (800 odd lists) of
an upcoming upgrade. How do I do this?

How do I send out a mail message to ALL list managers of ALL lists hosted
by this host ([log in to unmask]). I need specific syntax...if possible.

Our version is 1.8c.Is there a database/file/archive that I can check for
all the managers? Or do I have to "REV <listname>" 800 times to get 800
headers to retrieve ALL list managers, and the send out 800 email messages?
Please Help.

Thanks in advance.
