When a ride is posted on the calendar and a rider wishes to participate in the ride, there is a procedure where riders can "join the ride".  That would be helpful to the ride leader to know who might be planning to ride so no riders get left behind at the start and also so the ride leader knows he will have at least one participant on the ride.   Ride participants can also be listed after the ride is complete.   I'm not sure everyone is awware of this.  Percy if you have anything to add to these features, please do.
