You know where I'm coming from, Allen. I think the last guess was "String, or nothing!" (In the book, anyway.) It just came to mind when I noticed this thread again; the idea of the riddle being all important.
With that said, there's a few riddles here with no answer, or with unconfirmed guesses lying around. We need the riddlers to come back and put us out of our misery!
Credit where credit is due! Give kudos or accept as solution whenever you can.
