The Dead People Server, according to the home page, is "simply a list of interesting celebrities who are, or might plausibly be dead, and even those who have been spaced, with information as to who has really Rung Down the Curtain and Joined the Choir Invisible, and who's Just Resting." In short, if you want to know if it's true that Celebrity X is dead, you can check here. (The question might be raised, though: If you're not listed here, does it mean you're not dead... or just that you're not famous enough?)
