Have you used Webscorer? Would this work for Enduro?
Webscorer was used at the JABR for the timed sections. The volunteers learned to use it on race-day. I would suggest some experience before trying a weekday evening event with it.
Experienced with doing the Squamish toonies, and yes a points system gets more people out on a steady basis and seems to get more people involved with the club not just for racing but for that weekly social gathering of rubberheads. Its the social gatherings that makes the club stronger.
