@mikek ... Me either, but in the past I've just jumped in, found someone who knew what s/he was doing to collaborate with, and took a shot. Or even just took a shot on my own (although, I always need help with production). I still don't know what I'm doing, but I do my best. People on the forum are, for the most part, very willing to answer questions and generally help out.
If you're interested in giving it a go, don't let a lack of information or knowledge stop you.
