There are several types of listservers, and the commands, although
somewhat similar, vary from one type to the other. These
commands allow you to communicate with the academic network's listserver
(which is a program, not a person) so that you can set the options you
want your account to have with the academic network. Remember to send
your commands to your network's listserver address (not its regular
mailing address) and to put nothing on the subject line.
