I am finding your research utterly fascinating. When I was in University, I was a research assistant for a professor who was writing about fanfiction, and as a result, I got to audit the course she taught on it. What's different, of course, is that I was taking it from an English major's perspective, so we focused on the how, why, and what of fanfiction, rather than on the legality of it. (The author is god versus the author is dead theories, for instance.) I am finding this delve into the legality of it fascinating.

I'm also finding myself wishing more and more that I'd done my Masters in English like I planned - I was going to focus on fanfiction. XD
