Along with all the other suggestions, I would refrain from using NO... with the crowd yelling, the girls yelling, the coaches yelling, and their 10, NO and GO sound too similar.
I use GO and either STOP or BACK I have learned to not say NO
I agree with not using the No and Go terminology. As a matter of fact on third I use "score" or "back", and on 1st I use "two" or "back" and have totally eliminated no and go all togeather.
In the past, I don't know how many times the runner at 3rd has come back to the bag thinking she heard "no" when I was actaually saying "go". Doesn't happen anymore.
