I've had problems updating my billing info with the webhost, though I made another attempt today and hopefully it'll go through. If not, might possibly lose access to the files stored on uox3.org (though not the domain itself) for a short period of time following January 1, 2009.
Nah, I have backups. Also, I got a mail today confirming the requested change to my billing information, so in theory the end of the world should now have been averted.
