Hint 1: ALWAYS CHECK THE SOURCE! Right click and click "View Source" or "View Page Source"
Hint 2: When you see the characters <!-- in the source code, you'll usually find a hint right after it. ;)
Hint 3: If you think of an answer to the level you're on, replace the current URL ('help" in this case) with your guess to see if you're right!
Hint 4: Even if you put in a wrong guess, we might still give you a hint, so try everything!
Hint 5: Changing the URL will not always be the way to the next level... Try different ways if you get stuck!
