I came across this little repository of vast knowledge while looking for audio cueing software for the Mac. I currently volunteer running sound and lights for a community theatre group, mostly controlling, but also design.
I am definitely recommending you to my colleagues at our stage!
Welcome to the booth! I'm always preaching to gospel of Community Theater volunteering around here. Community theater is both a great way to start a career and a great way to just "play theater" as a hobby.
