Just when you thought it was safe.
http://www.rpgcitadel.com/maps/map2.phpOf course Google has an API that allows you to import their maps and make your own overlays!!! And of course there are a multitude of people that make those API's even easier to use. So of course, when I stumbled upon it quite on accident, I had to throw it up really quick.
This is the script I am using and it is a VERY simple interface. The most important instructions for me adding people is this:
To add a marker on your map, go to maps.google.com, double-click on the point you want to mark on your map and click on "Link to this page". Note: you must double-click or drag the map, not just search for an address. Now copy the resulting URL
and paste it here and I will add it. You can also add a few lines of text like I did. Once there are more people in it I will remove the auto opened bubble so that you have to click on it to see information.
(For those that dug down to see where I live, I put myself on Little Rock AFB which is about 8 miles from Cabot. That large building is really where I work though. Thought it was more interesting to look at then a freeway and a few buildings in downtown Cabot.)
