This tool seems so cool and I'm thinking about trying it this year. I might implement it into a point system...like if you earn 5 points on it, you get to pick a prize of that value, etc. But I'm wondering one thing. Is there a way I can clear those points? Say John has 8 points and decides to use points to get a 5 point notebook, leaving him with 3. Is there a way to adjust those points? I hope so!
