Okay something I forgot before but may have been implied anyway: Questioners are allowed, but not required, to give hints after asking their question.

Also
Rule 10. One guess per person per question.
Rule 11. The questioner is the final arbiter of who answered the question right first. Even if Poster X says that Abraham Lincoln was the first president of the US and the questioner says he is right, Poster X gets to ask the next question. The game must go on!
Rule 12. Minor misspellings should not be grounds for deeming an answer incorrect. The questioner has the discretion to determine whether the spelling of an answer is "substantially similar" to the correct spelling.
