Best to have someone experienced drive the organization, scheduling, logistics, etc. of setting this up. Definitely be helpful if folks who are willing to dedicate a little time to assist with the logistics and planning step up as well, so they see how it's done right, learn from it and attempt to organize it themselves next time around.
I'd be willing to help pitch in but never doing one of these before, I'd have no clue if I'd be doing it correctly or not. It's sometimes not about "set it up and they will come", it's also organizing and scheduling around a period where you'll get a decent turnout, of both folks w/gear and folks who want to come and stay to listen, socialize, etc. You may not hit 100 attendees since a Bay Area meet was just recently held (successfully from all accounts) and it may be too soon for another one. Mini-meets (ie. 3-6 folks) at someone's home might be ideal and easier to set up.
Just some food for thought here.
