I did the book item last year, but I did find it slightly frustrating (personally) when going through all 20-something posts trying to find one bit of information. So this year, I've opted to do static items. My folder will have 3 "main" items: One for outline work, one for character profiles, and one for setting descriptions. I will add to this folder as needed for things such as character background stories and similar challenges.

Here's what I have so far (the settings item isn't created yet): "Invalid Item"
