At the bottom of every message on this list, there is the URL 
http://lists.centos.org/mailman/listinfo/centos-mirror

Go there and remove yourself from the list. If you can't remove yourself, 
that page also tells you who the list admins are. Talk to them directly if 
you need help.

Shouting at other people on the list (people who aren't list admins) won't 
achieve anything.

also you can send a blank email to centos-mirror-leave@centos.org to be removed from the list

Ralph & Team, Does mailman have a direct unsubscribe link that can be embedded in the footer of every email much like the list info link is added would eliminate the issue for those too lazy to work out how to unsubscribe
