Accumulators would be fun if we had larger time scales. As it stands, Im not sure if I would bet on an event in a few months, unless I can tie it together with more recent events.
Either way, I think it wouldn't hurt to open up to future events. Some of the above concerns are valid, but anybody can choose to keep using vbookie as it is now, and ignore the later bets. So no harm done, right?
hit the nail on the head.
