As an event organizer I want to be able to contact all event participants at any given time to provide additional information, send over a feedback form or raise awareness for my event.
As a raise-awareness-function an automatic reminder function would be cool. Just set the days/time before the event in the macro and type in your custom reminder text.
@Michael Paulus: Very interesting idea, I added this as a separate request over here: https://linchpin.canny.io/events/p/automatic-event-reminder
@Daniel Roller: Thx and voted:-)
