I found my problem on this thread: http://en.forums.wordpress.com/topic/what-does-it-mean-sorry-this-site-is-reserved
The staffer wrote, "Contact Support with all the details. It might - but no promises - be possible to free the name."
How do I contact Support?
The site I want to create is countercoulter.wordpress.com. WordPress tells me it does not exist, but is reserved.
