I came across this site today while searching for answers to a question on one aspect of writing dialogue. In all honesty, I've only heard of one of the writers listed under Faculty, but the site seems to have solid advice and how-to articles that cover a wide range of topics related to fiction writing, and there are a LOT of them. I thought we might find it helpful.
