Ie: if you are hosting the game, tell your current IP address to everyone who wishes to join. They must do so over TCP/IP (if you are hosting using this protocol) and type in the exact ip address, in the form:
In order to find your IP address, in Windows, go "Start" then "Run" and type:
then hit Enter. It will display your IP address. That is the number they need to put in.
If they are stuck at "searching" for more than a few minutes, something is probably wrong. Perhaps they are behind a firewall or something.
