As you like exchanges, would you prefer to continue having "secret" exchanges, where you don't know what other requests are in the pool, or would you like to have "open" exchanges, where the sign-ups are posted openly?

Many exchange games have their sign-ups public, so that other players know what is potentially available. This has advantages and disadvantages. It's possible that if people saw what others were requesting, they wouldn't sign-up at all -- "Nothing for me here, not gonna play!" On the other hand, if the players could tell me which requests they actually want to write, perhaps we could have more happiness in the matching.

(Every year we've played exchange style, there's been at least one hurt, discouraged, or angry player because of a bad match. Some people have stopped playing entirely because of bad matches.)
