ConnectU
ConnectU (originally HarvardConnection) was a social networking website launched on May 21, 2004, that was founded by Harvard students Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra in December 2002. Users could add people as friends, send them messages, and update their personal profiles to notify friends about themselves. Users were placed in networks based upon the domain name associated with the email address they used for registration.
