Bad Fanfic! No Biscuit!
This is one of the first resources I used when I started writing fanfic for public consumption. If you've never written fanfic before or are still kind of new at it and want to improve your writing, I highly recommend this site. The lessons are taught with warmth and humor--not dry reading at all. Even seasoned fic veterans will find this a refreshing look at the fundamentals they (should) already know.
