I'm preparing a client for migrating his Blogger blog to a self-hosting WordPress site. The client is currently running his Blogger blog using a custom domain name which he registered through Blogger. Now that he wants to move to a self-hosted `wordpress.org` site, how can we transfer ownership of his domain name from Blogger to another registrar? Or, is this even necessary? I mean, can you set your Blogger domains' nameservers just like you can with any other domain registrar?
