Making a simple network connection

Hello I am very new to torque and I was wondering how I can make a very quick and simple online game in torque that all it has is your character and the characters of other people playing the game. I just want to try and establish a connection between my computer and others. Basicly what I want it to do when you open it is ask if you want to make or join a room, enter the name of the room if you are making it, and then click enter or create. Then it will just be a flat plain with the blue block character that's included in torque. Please help me because I have no idea what so ever on how this would work...
