This is my first post, and I'm not sure what should be said. Let me start by telling a little about myself. I am a 67 year old and retired. I volunteer at a community theatre as a master electrician and special effect creator. I started in the theatre when I was 8 years old and with my age, I have seen just about every dimming system and sound system that was ever built. I joined the forum, because I like hearing how high school and college students are learning the trade of technical theatre, and hope that I might be of some assistance to those that are just learning their way.
