You have been randomly selected to participate in the Beta Test of our new message list page. We've rolled out this test in order to get additional feedback and error reports from a wider subset of users. We'll only display this notice once, but permanent links to disable the Beta, provide feedback, and get more information will be located at the bottom of each message list.
You don't really need one. As far as getting through the game, it is very linear, and holds your hand through any of the puzzles that would otherwise require thought. If you have any other questions (such as Where do I find ___? or How do I beat ____?) check the answers section and the boards, and if you can't find an answer feel free to ask.
