Welcome aboard, Wendy!
We're all harmless, to mostly harmless. And the people here are really great! You'll make friends here with people who are at all stages of the profession, and they're very helpful.
If it's any consolation, I was pretty nervous when I started here, myself. I think I spent more time -under- the couch, than on it.
But with the help from the people here (especially Mac!), I finally sent off my very fist submission. If I can do it, anyone can!
Join in on the Weekend Progress Report, and get -alot- of encouragement, if you want.
