I knew Mojang was going to create an option to change your name, but it hasn't come out yet. Did they cancel it? I hope not, because I don't care for my name too much. Or is it still in progress? Can someone tell me?
They announced it as a possible feature, but that was a long time ago when Notch was still working on the game. They haven't said anything about it at all lately, so it's a bit doubtful it's ever going to be created.
