I get to work with some terrific people in the Forex world and top of the list is Kor, of Kor Harmonics fame and TradingArsenal.com. We've been collaborating on some harmonics quizzes over the last few weeks (though I should point out that my input has been mostly word-smithing, rather than technical).
