To clarify what I said earlier, you *can* create a challenge without a prize, it just has to be a Guild challenge instead of a public (Tavern) challenge. So to do that, you would create a Guild first, and then create your challenge for that Guild. Participants would need to join the Guild in order to join the Challenge, but that isn't a big deal, and they can leave when they're done. It would also mean there would be a Guild chat for people to ask questions or find out how the study turned out.
