I’ve been lurking around ControlBooth for awhile now. Though it’s mostly geared toward the lighting and sound kind of theatre technician, you can find some useful information for scenery or even props.
I just discovered the site has a whole section called “Collaborative Articles“. This is a collection of articles written, surprise, collaboratively. It’s organized alphabetically, and there is some useful information there.
We’d love for you to come out of the shadows and post a bit on Control Booth. We might deal heavily in lighting and sound, but we have plenty of theatre professionals in all aspects of Tech. Don’t be a lurker, it seems like you have a very active and successful life and could add greatly to the discussion.
