Mojang have announced on their blog, that soon you'll be able to change your in-game name in Minecraft. The feature will go online on February 4.
There are a few limitations to this feature however. Naturally you can't have a name that somebody else has already chosen, and you can't change it very often. There has to be a 30 day period between the changes. Additionally you won't be able to escape bans by simply changing your name.
Are you happy with your current name in Minecraft or would you change it to something else? What name would you choose?
