Send a command through email to listserv@artsci.wustl.edu. It is important that you send mail to listserv from the email address where you want the list messages to be sent.
The command to send is: subscribe SYSTEM-L John Doe

When you join a list, you are sent a little pamphlet. Do not discard it! Although they do look the same from a distance, the pamphlets are customised to the individual lists and do not contain the same information. You may need to refer to it when you have an administrative question about a mailing list.
You may leave the list at any time by sending a SIGNOFF command to: listserv@artsci.wustl.edu :
signoff SYSTEM-L
LISTSERV does not need your name for a signoff command, so there is no need to type it.
