Hi chasb, thanks for the feedback. The two links in the header are 'pricing' and 'privacy', because those are the two questions that come up most often.
What I've found is that if people sign up (a) either their parents start writing stories, in which case the price is not an issue or (b) their parents don't write stories, in which case they can just let the trial expire. Because of this, I'm optimizing for trial sign-ups so people can judge the value for themselves.
