Emergency contact person - automated emails
It might be nice when a trip happens (not a course or seminar, just a trip) that an automated email gets sent out to everyone's emergency contact person letting them know that they're going on a trip and what to do if they don't come home. If they don't live with each other, I bet nobody ever tells their emergency contact person they're going on a trip. I don't know what the official process is, but maybe the email could say "Sally Smith is going on a 1-day trip today with the Mountaineers, if they aren't home by noon tomorrow then don't call 911 instead call blah blah blah..."

maybe also add a checkbox in the account preferences for "Send email to your emergency contact person for every trip?"
