just don't know how to teleport players
Here is the link to the model if you want. You can also change the image and id too.

You may want to make a variable so your code is shorter down the track:
TS = game:GetService("TeleportService")
Then you can use TS:Teleport
to teleport a player to a game.
There are more TeleportService functions: http://wiki.roblox.com/index.php?title=API:Class/TeleportService
