Wow, Entitled Princess Fan is clearly a moron, are we sure she's even read your site? It's made pretty clear on there what you're opinion on emails like this are!

"I do hope that eventually you realize that your work is public property and that you learn to behave in a more professional manner in public forums like your LJ and the chat room on your site."
Also, she clearly doesn't understand fanfiction... because it's not public property and it isn't 'professional' - fanfiction writers are not actually, 'professionals' writing fanfic isn't anyone's job, even for the fanficers who do also write professionally!
