Add RSVPs to events
It would be nice if we could track who is planning to attend an event. The short events
output could display a number of planned attendees, while the long output could additionally list all of them. Reminders should probably always list them.
There should be instructions when adding a new event which specify how to RSVP. Reacting to the event would provide the smoothest user experience. The bot could add the first reaction, so that users don't have to find the correct reaction. This could be a custom reaction, like text that says planning on attending
.
There should additionally be a fallback method to RSVP, for those using clients that don't support reactions.
