A collaboration of both United Jewish Israel Appeal and TotallyJewish.com, Jewsreunited.com, a site operated out of the UK, aims to serve as a meeting point for reconnecting with your Jewish buddies from Hebrew school, synagogue, university, Israel trips, and more.

Unfortunately, when I tried to join, there was a severe lack of American Jewish organizations. This site may only be for British Jews to reconnect. All 100 of them.
