For a whole slew of virtual meetings, you might also be interested in visiting a key website courtesy of one of the major contributors and participants to BerkeleyLUG, that of Michael Paoli.
That webpage has a list of about half a dozen virtual meetings here in the SF Bay Area itself (including BerkeleyLUG's), and also lists a whole bunch of other virtual meetings around the US and beyond.
Note from BALUG's 'Virtual Meetings' list that the San Luis Obispo Linux Users Group -- which is a tad closer geographically to where you are in "socal ;o)" -- has its next meeting this very Thursday evening, October 1st. See

Hope that this also helps!
