Yes, we were screening to keep the details of requests and writing preferences anonymous - it should make the guessing more challenging! At least, that's what we hope, that nothing will be immediately obvious ... though of course there are always some people who are just very good guessers!
We're still taking sign-ups now, but we will probably post the list of participants before we cloister ourselves with the requests and our matchmaking duties ... just to give you something to salivate over while you wait! These holidays are going to be very full of Snarry, it's obvious already. :)
