For the listserv based lists, the following will work. The format above is in the form
which is the list address. To subscribe, send an Email to the administration address, which is
containing a single line:
subscribe <listname> <firstname> <lastname>
and replace <firstname> and <lastname> by your name (use only two words for your name). Do not include signature files or anything else, because the software at the other end tries to interpret your complete message.
For instance, if your (two word) name is Winnie Poo, and you intend to join stat-l, send the message
subscribe stat-l Winnie Poo
Some listservs may ask you to confirm your request in some way; pay careful attention to the messages you receive from the listserv, and follow the instructions. It is sensible to retain these messages as the information provided often has vital details of how to leave the lists and how to search associated files and archives of past messages. You can also retrieve other information and set options. Send the text help to the listserv address to obtain more detailed information.
To unsubscribe, send the message
unsubscribe <listname> or signoff <listname>
to the listserv address.
Automatically maintained lists typically offer more services. For example, lists like stat-l, which have lots of Email traffic and easily fill your mailbox every day, can optionally send only one message per day, containing all Emails from the last 24 hours.
The command set <listname> digest
(example: set stat--l digest), when sent to the list administration address, sets the digest option.
Send an Email containing the message help to the listserv address to get more detailed information.
