I definitely agree with everyone so far- talking to other chairs helps a lot.
My piece of advice is this: don’t be afraid to call your NSDA official. We’ve had a few sticky situations over the years & getting advice from the top has been incredible helpful- especially when looking for clarity on some of the more obscurely worded rules. We’re also very transparent when we seek advice from the top; in general, I call in TAB with all relevant parties present so that there’s no question about what was said.
I think sometimes people shy away from contacting the NSDA because they don’t want to feel foolish or embarrassed, but we forget that the officials at the NSDA live these rules for so much more of the year than most of us do.
