I just wanted to let everyone know that, in the interest of creating a more open community, we have created a "public" developer mailing list.
http://archlinux.org/mailman/listinfo/arch-dev-public
This list is read-only to non-developers (the list will reject your mail) but anyone can subscribe to it and see the archives.
We're going to try to do most of our discussion and things on this list, so if you are interested in observing, or just seeing what we do, feel free to subscribe.
