I used to run the blog http://www.100daystomarathon.wordpress.com. A friend moved the blog, so I can host it by myself. The new adress is http://www.runtravelgrow.de. My problem is: I cannot enter des dashboard of my old blog (www.100daystomarathon.wordpress.com) in order to delete it. I cannot use my admin name and password from the new blog. And I cannot use the regular wordpress admin name (philipplaage). So I don't know how to enter and delete the old one.
Could you help me with that?
