My events are courses with an instructor and a small number of attendees. Sometimes (usually because of too few registrants) an event has to be cancelled. If I select all registrants and cancel their registrations, the instructor gets n similar messages, and I still have to cancel the event. Could event cancellation please trigger a message that would automatically send a standard message to all registrants with a copy (or a variant message) to the instructor?
I’m disappointed that you don’t take your clients’ reasonable requests seriously. You have Default Message Templates that include a message to the Event Admin and a different one to each registrant. Why couldn’t you add one called “Cancel Event” and let the user customise it?
