To add teleporters is the easiest thing to do in my opinion.
Open your map within Sapien, and click the folder called Game Data. Then Click on Netgame flags.
This is where you set all the things for koth, ctf, oddball, race, and teleporters. Just set the option (youll see the button) to teleporter in. CLick somewhere, and then deselect that flag. Now make a new teleporter, only now you click teleporter out instead. Place that wherever you want.
Now ingame you wont be able to see anything, but to make them seeable, is just use the scenery tags (the plasma teleporter, and the little base for the teleporter) Now place the green sheild teleporter on top of the flag for teleporter in. Then set the base for the teleporter (its the green triangle with the gray surrounding's) at the teleporter out flag.
And there you go, teleports!
