I need to change the name of my blog (apparently there is someone out there with a similar name). I know I can change it on the settings… but will this also change my domain? Should I just set up new blog under a new name… and just route people from the old blog?
The domain name will not change, just the blog title displayed at the top of the blog. You change the blog title under settings > general and make sure and click “save changes” at the bottom of the page when done.
If you need to change the URL, you will have to register a new blog with the new URL.
