2014 Gambling Challenge - Possible Rule Change, please read

[Dartgod]

I'm considering a new rule that will not allow bets to be changed. I spend a lot of time entering all these into a spreadsheet (especially early on) and there are a lot of people that make a bet and then change it or cancel it. This adds to the time it takes me to keep this running.

So I am thinking about making the rule that once a bet is posted, it is final. They don't allow you to cancel or change bets at the sports books in Vegas do they?

I'd like some feedback on this before I make a decision.
