You know those pages that are in the back of most games intruction booklets that are blank so you can write little notes in them? Does anybody use those?

I used one for every Megaman game, I'd write the passwords to the levels in them. I used the ones that came with FF: Dawn of Souls so I could write down the HP of some of the really tough enemies and their weaknesses. I use the notes page that came with my Puzzle Fighter II game to write down my best scores and the cheat code to unlock Akuma.
