I made a very dumb mistake. I was creating a secondary blog with my user id, but then I wanted to create a new blog with a new email id but the with the same address. When I changed my blog's address from dullardandy to dullardandy1, I thought by deleting the former address, the url would be open to be used again, but now it says the author has deleted the address. It can't be used again.
Can I still retrieve the old url which is dullardandy.wordpress.com
The blog I need help with is dullardandy1.wordpress.com.
