Some answers (like people's names) have many possible variations. Where this is the case, I have put in every different possible variation that I know exists as acceptable solutions. Not only that, but this contest has been tested for quite a long time, and so the possibility of it having a mistake is fairly low. However, I can never totally rule out that possibility. So, if you think you have the right answer but it won't take it, send e-mail to me (BJ) explaining the situation and I'll see what I can do.
