I have only recently started using WordPress.com so I'm very new to all of this blogging stuff. I found a website called ProPhotoBlogs.com. On the site it says you must have a "self-hosted" blog with WordPress to use their product. It also says that if you have a flash BlueDomain site, you should have everything else you need to use their product. So, I have a free WordPress account. I need to know what, exactly, I need to do and what else I need to purchase in order to get this ProPhotoBlog up and running. I've clicked all around on WordPress's website and I can't figure out how to upgrade my account to a 'self-hosted' one.
The blog I need help with is sarahdianephotography.wordpress.com.
