Unsubscribing
If you want to leave the list permanently, with no intention of ever coming back, send the command:
SIGNOFF ATCA
to the listserv@listserv.icors.org.
If you are planning to come back to the list at some point in the future, follow the instructions for setting NOMAIL under heading #2 — Setting MAIL and NOMAIL. If you send the SIGNOFF command, you will need to go through the listowners to begin receiving mail again.
