Same rules as always - if you use the internets to answer these, don't post what you find in the comments thread, i.e., don't spoil it for anybody else (though guessing or actually knowing the answer and commenting is fine).
You might want to click 'Reply/Speak' rather than the link that will let you see all the comments, because that way you can type in your answers without seeing anyone else's.
