[Mailman-Users] Moved lists, URL's all fouled up.

Hi, I have lists that were originally configured for maillist.linuxmednews.com now I would like them to be configured for www.linuxmednews.com I've changed things under the covers and I can get to the main admin screen at http://www.linuxmednews.com/mailman/admin/mednews, login okay, but when I try to get to a submenu, it tries to change www.linuxmednews.com to maillist.linuxmednews.org which gives a resource not found, naturally because it doesn't exist. How/where can I change the lists old internal references to go to www.linuxmednews.com not maillist.linuxmednews.org?

Thanks,
