Geoffrey,
I talked to Cam Vilay last night, and he said he was interested in a California Chapter too (he has been since June '09.) Please add him to the mailing lists about Wikimedia California chapter creation. Have you heard back from anyone else on http://meta.wikimedia.org/wiki/Wikimedia_California#Roster_.28Join_the_cause... ?
All,
Others interested should sign up there and let Geoffrey know your email address. There will be a discussion at http://en.wikipedia.org/wiki/Wikipedia:Meetup/San_Francisco_13
Cary,
Do you expect https://bugzilla.wikimedia.org/show_bug.cgi?id=23022 to be created by the meetup on Saturday?
Cheers, James
