I accidentally signed up for wordpress.org instead of wordpress.com. Now when I try and set it up on wordpress.com, I can't because the username is taken on wordpress.org. I do not have the capability to go through and change the username on wordpress.org (I don't have hosting and not up for setting that up and going through wp-admin). Is there anyway to change my username on wordpress.org without having to set all of that up? Can someone just please delete this for me?
