To make the gate place your mouse where you want the gate on the map. Then write down the numbers assigned to the letters at the bottom of the screen like x:2423.34 y:343.67 etc. Then on the first tab of the map maker thingy under where it says gate coordinates or whatever you type in the number according to the letter it was next to at the bottom of the screen. The whole number wont fit btw just type as much as you can. REMEMBER TO WRITE DOWN THE COORDINATES BEFORE YOU MOVE YOUR MOUSE TO TYPE THEM IN.
