Yes, Loge, I think you are safe in saying your opinion will be ignored, I'm not going to monitor which Quiz to allow and which not.
However, I'm very interested in what you say about hints not being possible for a lot of Quiz questions. Are you saying it's far easier to give hints for crossword questions than it is for quiz questions? Why can't you give hints for Quiz questions.
A simple example for which I have given a hint. Surely this could apply to other quiz questions.
Question - A yellow river in Derbyshire
Hint - Think of a village on the A6 trunk road
PS - We've digressed away from Save the Children Quiz but the original questions have been answered so I don't think it matters.
