Hey I found this in a thread and thought I would revive it. Its simple on the upper part of the screen you will see a button that looks like a marker, its to the right of the "hand". if you hold your mouse over it, it will say add marker. Place that marker at your location. I personally found my location first, so I had a place to put the marker. Press that and then where it says "point***" change that to your 6x6 world name. Even if you just place it in your town center it will be great for helping find riders close by. You should have already logged into your google account, if you want to be able to edit the map and place your location on it.
