I screwed up my initial domain name and now I wish to change it.
There is a small (24 hour) window in which we can cancel a newly-registered domain. Sadly, it appears you registered yours back on August 30th.
I recommend sending an email to support@sonic.net explaining your situation (it looks like you signed up for Personal Hosting w/ one year free registration) - chances are that the hosting setup can be moved over to a different domain.
