I want to change my WordPress.com username from "arunsathiya1995" to "arunsathiya", but I'm not able to do so because "arunsathiya" already exists. Actually it was me who used both the usernames. The email ID associated with "arunsathiya" is closed now and so I'm not able to change now. Help needed badly.
The blog I need help with is 404geeks.com.
