The MacGroup mailing list.
We also have a great Macintosh email discussion list.
It's name is "macgroup".
Anyone interested in exchanging Mac-information, asking Mac-related questions, passing on Mac tips, etc. or in general helping each other along the line can participate. It is FREE. Tell all your Mac friends to sign-up; the more the merrier.
To join:
Send email to majordomo@erdos.math.louisville.edu containing the single line
subscribe macgroup
A few minutes after you do this, you will receive two messages from majordomo. One will be general information and instructions. The other will contain instructions how to confirm your subscription request.
(The reason for this baroque procedure is to cut down on spamming.)
How do I unsubscribe from MacGroup?
Send email containing only the one line in the body
unsubscribe macgroup
to the address majordomo@erdos.math.louisville.edu. Make sure your mailer does not automatically append anything else to the message, and it's best to send the message as plain text e-mail. The return address on your message must be in the database of subscribers, so send the message from the same account you use to receive mail from the list. You should get an acknowledgement from the Majordomo software a short time after you unsubscribe. If this acknowledgement does not appear, something went wrong. More information about unsubscribe and other commands is available by sending e-mail containing the single word "help" to majordomo@erdos.math.louisville.edu.
If you change e-mail accounts, please remember to unsubscribe from your old one and subscribe under your new address.
