If you want to subscribe Pigi mailing list - there are two ways to subscribe to a mailing list:
1. Send an e-mail to majordomo@pigi-project.org and type "subscribe list" (without quotes) in the message body.
2. Send an e-mail to list-request@pigi-project.org and type "subscribe" (without quotes) in the message body.
The steps to unsubscribing are identical to subscribing except that you replace the word "subscribe" with "unsubscribe" in the message body. Majordomo will send you a results e-mail if the subscribe/unsubscribe was successful.
