I was wondering how to import my blog.com blog to wordpress.com. I noticed it is not in the list, but they allow me to export it into .XML file, but there is nowhere to upload it.
Blog url: http://heavenforbros.wordpress.com/
If we do not have an importing tool for your particular platform, you will need to try and convert it into one of the accepted formats so that you can use the proper importer. This means you first convert your blog to one of the services mentioned above (such as Blogger), and then import your blog from Blogger to WordPress.com.
