The Ferret Mailing List (FML) is strongly recommended.  To subscribe
to the FML, send email to its moderator, Bill Gruber, at
<ferret-request@cunyvm.cuny.edu> and ask to be added.  You can
also try subscribing automatically by sending email to
<listserv@cunyvm.cuny.edu> with the command
SUBSCRIBE FERRET <first-name> <last-name>
in the body of the email.

You'll get a note back detailing policies and such and explaining how
to send letters to the list.  Back issues of the FML are available by
sending the command INDEX FERRET in the body of email to
<listserv@cunyvm.cuny.edu>, and an unofficial WWW archive at
<http://ferretworld.com/>
is also available, though not quite as complete.

The Ferret Forum mailing list tends to be shorter and perhaps more
international in flavor than the FML.  To subscribe, send email to
<majordomo@bolis.com> with a blank Subject
and either 
"subscribe ferret-forum" (for the regular version) or
"subscribe ferret-forum-digest" (for the daily digest)
in the body of the message (no quotes in either command).

The "Ferret Tails" mailing list is a digest of ferret stories,
adventures, poems, and other entertainment.  Email
<kingfshr@northcoast.com> with
"subscribe ferret-tails <your email address>" in the body of your
message.

There are other mailing lists, too, including several regional lists.
A list is available at
<http://www.ferret.net/ferrlists/>,
or email Christine Code at <cmc@portal.ca> for information.
