It looks like you haven't registered the domain name codemolay.org yet. You can register the domain through your WordPress blog's dashboard for $18/year; this will associate the domain with the blog, and allow you to access the blog via the domain.
Do note, however, that you will still be limited to the constraints of the WordPress.com platform. For instance, you won't be able to upload any custom content you've created using Dreamweaver or a similar tool.
If you let me know whether you're looking to associate codemolay.org with codemolay.wordpress.com, or with a new blog, I'd be happy to let you know the steps you'll need to take.
