It doesn't matter what address we use, but the mailing lists should NOT be supported by the same server as the website. Because when the web server goes down, then we can't talk to each other.
By the way, if Maveric wants to take on the heavy duties of administering the mailing lists, we should probably accept his help. He's got the personality and aptitude for it, and he's well liked.
