When my first Petzl Zipka headlamp finally broke, I bought another one. That is a sure indicator of the right gear for my style. Enough light, light enough (69g), and it fits in my pocket.
Our troop has an e-mail alias that can be CC’ed for any communication between an adult and a Scout. To satisfy the “no one-on-one contact” rule, we respond to a Scout’s e-mail CC’ing yp@our-troop. The mail goes to the Scoutmaster and the Committee Chair.
I do this all the time, even when working at a District level, approving Eagle Scout service projects.
