Suprisingly...A Fanfiction Fan

I finished reading Ch4 and decided to give fanfic a try. I checked out fanfiction.net for the first time and I must admit…I liked it! I also checked out fictionalley.org and even godawful.net. I am not a big TV fan but I do love Law & Order. There were tons of stories related to the show. How cool! I am not one to really write my own stories and post them I thought it would be great for my students. I teach 8th grade English and fanfic would really allow them to express their creativity. Has anyone had their students post onto fanfic? How did it go? I assume some parents might not approve?
