I think a map with the locations of all members who wish to be located would be a great idea. This used to be possible through the now-defunct Frappr site, but I've been told that it could be accomplished through Google Maps with a little knowledge of script.
Does anyone else think that this is a good idea?
Added: Pin your home court location on the map: (Gmail ID required)
TO ADD LOCATION:
I figured it out. click the Edit button on the left, and then right click the spot that you want to place yourself and click "Add a placemark".
Edit: In case of privacy issues, please pin location of your home courts instead of your residence.
