getting started

hi guys
how do I create a worker's name?
I am in USA, I just got a D3 and I have a S7 where I use slush pool, it took me 5" to set it up and make it work
here things seems to be different, please I need some help
thanks

here you do it in 1"
URL: prohashing.com:3333
Worker: <username you chose to log in to Prohashing>
Password: n=<random worker name, just for yourself to distinguish between your devices>

And if you are using a D3 to mine X-11 coins....Also add to the password a SPACE and then a=x11
So it mines the X11 algo instead of the default SCRYPT.
