Hey check out this cool mod I found...
http://www.agigames.com/board/index.php?action=worldmapThis allows all of the members of my site, board, and uploader to place a pin on the map showing where they are. They can move their pins around and see who other pins are.
If you would like to try the map out register at either:
http://www.agigames.com/site.php?page=memberhttp://www.agigames.com/board/http://www.agigames.com/games/then you should be able to place your pin on the map.
Please note that you will only have to register at 1 of these pages because when you register it is global which means you will be a member of all of those pages.
