To subscribe to the ACM@UIUC SIGCAS list send mail to: firstname.lastname@example.org
Put "subscribe" in the *subject* field of the letter. You can also send a letter with "help" in the subject field and you'll get a short help file.
You can do this from your unix account with the command:
mail -s "subscribe" email@example.com < /dev/null
To unsubscribe to the ACM@UIUC SIGCAS list send mail to: firstname.lastname@example.org with "unsubscribe" in the subject field. I have most people added with their ph alias.In the event of an address change, it would probably be the wisest to first send an unsubscribe for the old address (this can be done from the new address), and then a new subscribe to the new address (the order is important).
