It was indeed for the original poster. I agree anyone who answers has no way of knowing the quiz rules unless they themselves are taking part in that particular quiz. I completed and returned my entry last week so I was not looking for answers when I noticed this posting.
Oh, I think many of us have, Furrypusscat!
And it is annoying when you realise that you may have unwittingly spoiled an excellent quiz, and the setter's efforts at fairness.
Good luck, anyway!
