I'm trying to get my new hosted site set up. I've already imported all of the content from my free WP.com blog to my new hosted blog. I've been messing around with getting things set up, and have completely screwed up my comments and categories. Is there any way that I can delete the entire contents of what I imported from my free blog, and then reimport all over again to start anew? They seemed to all be correct when I first imported. Do I do this from my cpanel? Help, I am a total newbie to this.
