I used my current username to register a new blog. Then I realized that I would have to post on the newly-registered blog with my current username, and I'd prefer to post with a new username. Of course, I can't register the username I want, because it's the same as the blog name I just registered. When I try, I get a message saying that blog name is taken. And it is. By me.
Is there a way I can register a new username to post on my new blog, without registering another blog name?
The blog I need help with is bilinguish.wordpress.com.
