Greetings;

I've been reading The Official Forum for a few days now and have enjoyed the wisdom and wit, especially from the Senior Members. Laughed out loud at a few good ones and decided to become a member myself. Became a MHSAA registered basketball official this year and will start out with some city rec leagues. Already do slo-pitch softball as an ASA ump. Been studying the rule, case, and mechanics books, and as a former player and coach, I never realized how much I didn't know! I would like to advance slowly but surely. Any advice will be appreciated.

One quick question: What is the correct signal for a moving screen?

Thanks
