The statement above is correct. The bold holds true.
Feel free to send PM (private message) myself or any of the moderators and they will get the request to me. Posting in this thread is not the best way to get the message to a staff member to help with getting a username changed.
Again we do need a good reason as to why. 1000's of members and millions of usernames in the system. Not all will be available to changed to.
