The best ones were never written down.
An old house, a disappearance, the thing your grandfather wouldn't talk about. If it's true and nobody's told it, write it down and send it. If the fool tells it on the channel, you get the credit in the episode. First name, or no name. Your call.
Put the place and the year in the first line. Don't send anything about a living person you can't prove.
