You go to your zwinky account press f3 then c and hold them down the a different box should pop up and you put your new zwinky name in there and then if it dosent work log and then log back in.

Wat do you think is going to happen???? you are going to get a new box and you are going to put the user name in it that you want it to change to and them you push are you sure and then u log off and see if it work!
