Please save the introcutory message from the list for future reference,
especially if you are not familiar with Listserv. This might look like
a waste of disk space or paper now, but in 6 months you will be glad you
saved this information when you realize that you cannot remember what are
the lists you are subscribed to, or what is the command to leave the list
to avoid filling up your mailbox while you are on vacations. In fact, you
should create a new mail folder for subscription confirmation messages
like this one, and for the "welcome messages" from the list owners that
you will occasionally receive after subscribing to a new list.
