I just contributed my first game (
Soundtrack to Mayhem). I don't have a single source for the game; in fact, for each question, I used a combination of IMDB, wikipedia, and youtube to come up with complete information for the clue and the answer. I don't know how I would cite those as sources, or if I should even try. There wasn't one website or book that I could find that contained all the information for my quiz. Of course, we all would like our quizzes to be featured, and I would like to know how applicable "It should include a valid source (if applicable)" is in cases like this. Can I just cite IMDB, since I confirmed the answers on the Soundtracks sections for each movie?
