change name client side

How to change someones name clientside? There was a program year ago, but it isnt working anymore.

try searching for it in the linklist at my signature :)

Use CE (Cheat Engine). I made a post about invisible player, and i also changed my name, guild name, server name, and level with CE in that pic (Cant see the lvl part tho lol, too bad). Basically, do a TEXT search for your name, and then alter the results.
