From Feb 4th, we're going to be able to change our minecraft usernames at account dot mojang dot com slash me. You can change once every 30 days.
Why is this in suggestions? I thought it would be a good idea to have a place where people could post to say, "Hey, I changed my name from bluh to blah! But it's still me!"
I suggest a simple format which makes it easy to read through lots of posts at once, something like:
My old name was: oldname
My new name is: newname
It would probably be a good idea not to do any posts like, "oh cool I'm gonna change mine to bluh" until you've actually done it, just in case bluh is already taken, or in case someone else takes it before you!
much love,
