I'll do the Open Championship on the 17th of July. It won't work the way you mentioned but we can get it to work. I'll just update the odds and add/remove players if needed. Players can't be removed, but they can have an *, or something, next to their name and no odds. That way no-one will bet on them.
No idea on plans to bet on the draft.
Awesome Rajah, this can be used as a tester too. If it doesn't get many bets then we won't need to worry about it next time.
