you can email
support@hitechcreations.com and they will gladly change it in minutes (unless the name is already used, then you have to choose something different)
you will however have to rejoin your squad.
you will have to reform your squad if you are the CO / founder.
you will lose all perks.
you will lose all scores.
basically the new name is just that a new player. they dont have the ablilties of transferring your stats. if they did we could all change names 10 times per week LOL
imagine the headache for HTC staff if that was the case.
if you are talking about you name here on the bulletin board, that is not connected to your in-game name. you can create another BB account easily, and use whatever name you want (unless it is already used).
