The selection about wanting e-mail can be used for shooters who may shoot an occasional match with your club, but don't want to receive all your regular e-mailings.  In the E-Mail Wizard, you can specify whether or not to include "don't want" shooters.

Shooters who are certified as Safety Officers can be sorted on the shooters lists and on match registration screens.

Use Alt+Insert to paste information from the last shooter's record you had open.  (If you're entering a wife or a child, for example.)
