As a meeting attendee, I would like to get an email notification a couple of days after my event to remind me a) who was there (Yes's/Maybes) and b) suggest that I follow up with them. "Did you enjoy the xxx event? Below are the attendees. Consider sending a follow up message that says "yyy". Where yyy would rotate and say "Nice to meet you", or "Would you be interested in having lunch?" or "I really enjoyed what you had to say about that one topic".
