I'd add a few thoughts (not too far from plenty of views already expressed):
-A TO should act with discretion when it comes to new coaches or coaches who do not frequent the NAF site / TFF etc. and consider awarding the bonus anyway to these guys (share Joe's concern on that point).
-Payment in advance is a little controversial as there is a risk of punishing those with cash-flow problems. Though I know full well that TOs need money in advance so the event's finances can be planned. Tricky one. Again, discretion would be advisable in the event of a coach simply being unable to meet a deadline because of lack of cash.
-Incentives that don't involve in-game benefits are something I would also encourage and with a bit of imagination I'm sure TOs could come up with cool ideas to encourage people to pay up front.
-Pre-loading score with races is helpful, and I think it's perfectly reasonable for a TO to ask for races in advance, and to incentivise this.
-As to the indecisive roster tinkerers
