you can change it in he muli-player menu. Or you can change it in game but hitting the ~ "tilde" key and bring down console and type /name "whatever" 1) From the main menu select Multiplayer options. 2) Highlight the name field and remove any existing text. 3) To color your name you must insert "^x" before the letter you wish to color, "x" representing one of the numbers below. Each number refers to a specific color. Thus, if your handle was "Player" printed in blue, you would enter "^4Player" as your name. 0 = Black 1 = Red 2 = Green 3 = Yellow 4 = Blue 5 = Cyan 6 = Magenta 7 = White
I believe 8 works too, it's just not a specific color, if i remember correctly it changes depending on which allied team is on that specific map.
