Thanks for your comments Mamyalynne, it just annoys me that people repeatedly keep asking for answers, get them and then as you say, disappear! I will learn from it as you say. In most of the quizzes the prize money is minimal, so that isn't why I enter, it is for keeping the brain active and the fun of it.
Yes Smouse, maybe I didn't make that quite clear, I did mean that if people feel they have little chance of winning, they may not enter if the quiz is not complete.
