HelpGmod name spoofer?

Hey, I was on here and somebody posted that it was possible to spoof your name on gmod using cvars or something like that. It works so that your actual steam name doesn't change, but your name in server does. Does anyone know the commands to do this? I would like some help as I am new to gmod "hacking"

There is already a thread about this
It was just made
Try reading other threads, especialy when you're looking for a name spoofer and there is a request for a name spoofer
But anyways, it is possible, no idea how.

It is possible, look at the Source Engine Net Channel.
