I know it's important, but I'm not ignorant to the fact that if you want to play, you have to pay.
I have an abacus that was modified to accept about another 10 numbers if you want to borrow it
Why bring up the expense of things???
Because it's important!!! Our club is already scholarshiping one or more kids state tournament expenses each year because their parents can't afford it. We don't need any added expenses and I'm sure many many clubs/parents feel the same. Besides, I broke my abacus trying to decipher your referee assignment formula.
