The puzzle I have in mind is this one.
I have an incomplete idea to solve a riddle, but I want to share it so that other puzzlers might have an epiphany and come up with an answer. My incomplete idea is something along the lines of: "I have a pretty good hunch the puzzle works like X, and I can make a few interesting connections, but I haven't figured it out."
Is it appropriate to share my incomplete idea? If it is, would it be in the comments, or in some kind of WIP answer?
