I have problem with subdomain name. I made blog address ebayshophr.wordpress.com on my account. Then I decided to transfer blog to my other user name. I deleted blog address name ebayshophr.wordpress.com and that I tried to rename my second existing blog kupoprodaja.wordpress.com to ebayshophr. And now I get message saying Sorry, that site already exists! but it does not exist anymore since I have deleted it. If you go and check address you will see it does not exist. Could you please check that and make it available in any way. The original ebayshophr was made on my account by username Oseloth if you need it for reference.
Blog url: http://kupoprodaja.wordpress.com/
