The unofficial days of the Wah Yan San Francisco Alumni Chapter started way back to the late 1980's, when Internet access was limited to those who worked in the computer industry or associated with research/higher education institutions.
Back then, there was a Usenet communication forum mostly participated by users from Hong Kong. Three Wah Yan alumni (Vincent Yau, Charles Mok, and Kelly Chang) "met" each other on the Internet and started the "Wah Yan Net", an email mailing list. The list gradually grew to a couple of hundreds. Some of the members who resided in the San Francisco Bay Area decided to meet face to face. It was an cooperative effort. Those who had email access relayed messages by telephone to their Wah Yan friends who did not have email access. On a Saturday afternoon in 1989, about thirty Wah Yan graduates showed up at Fook Yuen Restaurant in Milbrae for lunch. Thus the unofficial chapter was conceived.
There were regularly lunch gatherings approximately once every two to three months, and occasional picnics. The primary communication was by email and relay via telephone to those who did not have email access.
