Is the attendee list in post #2 up-to-date with the Eventbrite registrations? I noticed that the Eventbrite registration form doesn't request a Head-Fi username, so I'm not sure how you're tracking the attendee list and matching registrants to Head-Fi usernames. I know Eventbrite makes organizing easier but that also makes it inconvenient for those who'd like to see who's attending....
The only reason I'm asking is because I'm considering re-scheduling my CA trip to coincide with this meet, but depending on who will be there - i.e., I'd like to catch up again with familiar faces.
Btw, any discount for out-of-state travelers? The SoCal meet in August last year had one.
