I'm new to WordPress and couldn't find a way to change my blog URL from daniellestepper.wordpress.com (my actual name) to entertainmentpsa.wordpress.com (the name of my blog). I decided to add a new blog under that URL and start from scratch. After doing so, I discovered how to change the address, so I deleted the new URL and went to change it - but now it's telling me that I can't have it, because it already exists. I definitely deleted it though, so is there a way to make that address available again so I can use it? It only already exists because I created it! Please help.
The blog I need help with is daniellestepper.wordpress.com.
