The Truth About Selling Fanart
Update notice as of January 17, 2013: I have given this guide a MAJOR overhaul. It was originally written over a year and a half ago, and since then my own views and understanding of copyrights has changed. I felt that this guide should reflect those changes, so if you read this guide in the past, please take a moment to look through it again as I have added MANY new topics, information, and sources. Unlike my first draft, I have also changed my viewpoint to neutral throughout this writing.
