Remind me what's changing on February 4th?
You can change or edit that embarrassing Minecraft username that you registered four years ago.
Unpaid Minecraft usernames will be available to anyone who wishes to change their name or buy an account with that name.
If a name was unavailable to register in Minecraft because it was registered in Scrolls, you will now be able to change to or buy that username.
