In November 2003, upon the referral of Victor Gao, the Winklevosses and Narendra approached Mark Zuckerberg about joining the HarvardConnection team. By this point, the previous HarvardConnection programmers had already made progress on a large amount of the coding: front-end pages, the registration system, a database, back-end coding, and a way users could connect with each other, which Gao called a "handshake". In early November, Narendra emailed Zuckerberg saying, "We’re very deep into developing a site which we would like you to be a part of and ... which we know will make some waves on campus." Within days, Zuckerberg was talking to the HarvardConnection team and preparing to take over programming duties from Gao.
