Hello guys i searched the forums but all the threads i saw were from 2006,2007 is the server creater up yet ?

From the in game main menu...
Multiplayer -> Create
Type your server's name, shows up under the "Room" thing on the top
there we go

My friends cant see when i do like that D:
And how can i change the pkayer limit,map,mod ?

They can't see?
Tell them to type
/jo servername
That makes them to join the server you made.

You can find all server commands here.

thanks
