Though some of my favorite people write fan fiction, I see her points in a way. Though, in HP, up until recently, author had said no more new books… There are too many shades of grey for fan fiction, like fan art, especially if you’re making money from them. However, even though I hate pirating. I think taking characters and “shipping” them with characters from other worlds, isn’t copying the story. The authors clearly never meant for Gandalf to meet up with Harry Potter, for instance. But, as we write Fan Fiction (which, in my opinion, is a great way to PRACTICE writing), we need to think of these things and what we’re doing.
PS I’ve never written fan fiction.
