RE: Active.com registration
I've used active.com to register for several events (cycling only). In my experience it works great- except for those few events where openings fill up within just a few hours of registration opening. Active.com simply cannot handle this kind of traffic and who gets to finish their registration before being kicked out is luck of the draw more-or-less. For events like this (I'm thinking of the Horribly Hilly Hundred in WI) Active should have a pre-registration- then chose names in a lottery from that pool.
