I will be switching my email addresses from @ferret.dyndns.org to @mail.aom.geek on or after September 1, 2001, but not until after Debian's servers include support. 'geek' is an OpenNIC TLD. See http://www.opennic.unrated.net for details about adding OpenNIC support to your computer, or ask your provider to add support to their name servers.
