Attendees
Who came to an event. The association never recorded it, so the archive holds the people who spoke, organized, mentored, or collaborated, and nobody else. The one figure is the Meetup RSVPs.
We don't track that!
8,917 Meetup RSVPs is the sum of the "RSVP: yes" answers on Meetup over the 267 meetups whose page records the figure, of 268. It is the number the home page prints.
An RSVP is a promise to come, not a seat filled: the people in the room on the day were more or fewer than that, and nobody counted them. The association never recorded who came, so nobody who only attended is named in this archive. It names the people who spoke, organized, mentored, or collaborated, because a program, a board page, or a credit names them.
