It would be nice if the planner of an event would get emails (or have the option of getting emails) when people RSVP to the event. Especially when that person leaves a note. Rather than having to check and recheck multiple times to see if additional people are coming. Or if a person leaves a note with a question, it would be nice to get a notification so you could address things promptly.
The event organizer getting a notification when a note is added to an event would be extremely helpful.
