Update mailing list docs - How to unsubscribe?

Hey everyone, I have been trying to unsubscribe from this list. I've gone through the directions at http://www.ezmlm.org/ezman/ezman1.html as suggested by http://us.php.net/mailing-lists.php. They don't seem to apply for these lists as written (the method listed for unsubscribing involves sending an email to mailinglist-unsubscribe@example.org, which in this case would be mailinglist-unsubscribe@lists.php.net which sends back a lovely "invalid email address" response). A little guidance would be fantastic, thank you! -Matty
