Redirecting Traffic

Hello all,

I recently switched from wordpress.com to wordpress.org. Now since I switched over to the .org version, I’m assuming I took the domain name with me. The old blog with the bought domain was at http://knowxone.com but now I am at http://knowxone.com/blog and the first site does no display. How do I go back & redirect traffic to the new blog? The only way is if people type in http://knowxone.wordpress.com and that’s too much of a hassle.
