I realise that this is borderline spamming, but I still thought posters here would be interested by that World Today Quiz. It has five difficulty settings, and contains questions covering the whole planet, from elections in Brazil to Chinese economic growth. Better yet, visitors are warmly encouraged to submit additional questions. Relatively easy questions are the most welcomed though, making impossible one is too easy If enough people participate, this has the potential to be a very, very interesting Quiz. BTW, there is also a "World History" and a Science & Technology quizzes on the same website. Have fun!
