I've configured two mailing lists on elinux.org:

announce@elinux.org:
http://elinux.org/cgi-bin/mailman/listinfo/announce

wiki-dev:
http://elinux.org/cgi-bin/mailman/listinfo/wiki-dev

I've linked subscription forms from the wiki here:

http://elinux.org/ELinuxWiki:Mailing_List

Let me know if there are any issues with them, or if you have any requests
for new lists.

Cheers
Bill
