Your RSVP matters!
When an event has a capacity limit on the number of "Yes" RSVPs, it is very important that you keep your RSVP up-to-date. If you RSVP and don't show (i.e. no show) your membership in the group is much less appreciated. No-showing will get you kicked out of the group.
When appropriate, event descriptions will contain an RSVP cutoff and that is your guideline. Even if the cutoff has passed, please notify us of your RSVP change so that we (a) we won't wait for you, (b) we can try to give the venue a more accurate head count.
