2. How to unsubscribe.  Send a message to

IAOBRIEN-request@rootsweb.com
that contains (in the body of the message) the command

unsubscribe

and no additional text.

3. How to re-subscribe.  For future reference (for instance,
if your subscription is cancelled for whatever reason and you
want to re-subscribe), just send the command "subscribe" to
IAOBRIEN-request@rootsweb.com
4. How to change to digest mode (several postings are combined and
sent to you together as a single large message).  There are two
steps.  First, send the command "unsubscribe" to
IAOBRIEN-request@rootsweb.com to discontinue mail mode.  Second,
send the command "subscribe" to IAOBRIEN-request@rootsweb.com
to start receiving digests.

5. How to change to NOMAIL mode.  There is no formal NOMAIL mode.
All you have to do is follow the directions above and unsubscribe
when you want the messages to stop, and then when you want them
to start again, simply subscribe again.

6. If you'd like to post a message so everyone on the mailing
list receives it, just send it to IAOBRIEN@rootsweb.com.  It
will then be sent on to everyone in both mail and digest mode.
You don't need to send it explicitly to both.
