subscribe [password] [digest|nodigest] [address=<address>]
Subscribe to this mailing list. Your password must be given to
unsubscribe or change your options, but if you omit the password, one
will be generated for you. You may be periodically reminded of your
password.
The next argument may be either: `nodigest' or `digest' (no quotes!).
If you wish to subscribe an address other than the address you sent
this request from, you may specify `address=<address>' (no brackets
around the email address, and no quotes!)
