When I first created my blog, I had a certain name for it (I'll call it OLDER). Now my site goes by a different title (NEWER) but of course the URL still says the OLDER name, which is a little confusing, obviously.
I want to change it, but I know you can't just edit it. Would it be as simple as buying a new domain name for the blog and making it the primary domain in the Domains section? Or would something totally different need to be done?
The blog I need help with is crosslenz.wordpress.com.
