Have the option to set a minimum on an RSVP option. This will indicate to users that if a minimum threshold isn't met, then the event won't happen.
This would be really helpful and I'm surprised it's not implemented yet. For scheduling things like TTRPG or boardgame nights, for example, you usually have a minimum amount of players you need for it to make sense to hold the game. Basically, ideal would be an event of - minimum 3 participants - maximum 5 participants - waitlist for other interested people - RSVP cutoff date, to declare a point in advance of the event where we need to have enough people, or it's not happening - automatically put a very noticeable marker on the event declaring that it's not happening, if the minimum RSVP count wasn't reached by the cutoff date. - allow a manual override of the happening/not happening state, in case someone pulls in the necessary amount of people from out of Discord. With the latest update's _Close RSVPS early_ feature, Sesh is very close to being able to do this. It just needs a good way to handle the question of "are we even enough to do this thing?".
