Does anyone know how I can change the site’s URL? I used something to experiment with how everything works and now that I figured most things out and have them like I want to, I would like to change my blog’s URL to something more relevant. How can I do this?
You cannot edit any URL. If you want to change the blog address ie. the URL starting with http:// then you must be logged in as Admin under the exact same username account that registered the blog to do that and the URL you desire must be available. If so then you can change the URL by using this guide http://en.support.wordpress.com/changing-blog-address/
