Oh man, yes, I read everything in sight for months before I said a word. I probably went through like 200 threads, saved a bunch of them, even wrote comments in my head and then deleted them before hitting send. What finally got me was a post where someone asked a really basic question about lighting and nobody had answered yet. I knew the answer, it was easy for me, and I felt dumb just sitting there watching them get no reply. So I typed three sentences, hit post, and my heart was pounding like I'd just jumped out of a plane. It's funny how scary that little reply button feels when it's really no big deal.
