Geez, now I'll be racking my brain to remeber what it was that we used many years ago to do this. It was an early app (before they even called them apps) that allowed you to sign in and identify your location. This became a map (US (even the World)) where others could see pins of where everyone was located. I'll bet the map(s) still exist, but I just can't remember the name of the product or site. I think, if I am recalling correctly, that Greg Susong was part of it or ???

Any long-timers here remember the product?
