- The Linux serial mailing list.  To join, send email to
majordomo@vger.rutgers.edu, with
``subscribe linux-serial'' in the message body.  If you
send ``help'' in the message body, you get a help
message.  The server also serves many other Linux lists.  Send
the ``lists'' command for a list of mailing lists.
