I have never had any of my fan fiction, or my original fiction for that matter, beta'd. I just haven't found someone that I trust that much I guess. I write differently than most writer's i have come across. Spelling and grammar really doesn't matter to me as much as the character I am writing about. I can always go back and fix that stuff later. Which means my poor Beta would have to be a English giant. :) It's also hard for me to express what i want from a story at an particular time. I will write paragraphs at a time just because I though up a cool line. I am very chaotic when it comes to writing. So my Beta would need to be able to deal with me being all over the place 90% of the time.
