Welcome aboard! I'm particularly glad when somebody mentions electronics... my favorite subject.
Anyhow, while this board is mainly aimed at high-school and college-level theater tech students, it's open to anyone with interests in that general direction, including old farts like me. You'll find very little in the way of ego-centric argument on these boards, just good people of all skill levels sharing information on the principle that "all of us is smarter than some of us." Feel free to join the discussions, ask questions and express opinions - that's the way we all learn.
DVS Dave, our webmaster, should be along to give you the official welcome pretty soon. He's a pretty good guy despite his propensity to root for the wrong baseball team.
