As well as sending the PM to clagmonster that I referred to earlier, I have also sent a PM to adtrainz who wrote this quiz (as it was I and another forum member who helped him to set up this existing quiz from a "beta" effort that was called Sugar Loaf) and the rules that appertain to it, especially as it is not specifically stated in the current rules about a challenge to a completed leg, from which a new leg or legs have subsequently followed on from.
We are only ten days away from the second anniversary of the quiz commencement and indeed, this sudden contretemps has cast a shadow over matters.
I appeal to Trainfan344 not to carry out his stated intention. He was in seventh place with 1,343 points on the last published September 2013 points winner league table and indeed, I totally understand his frustration at being told that he had lost the large number of points that he had won from the leg that was queried. He had done nothing wrong whatsoever.
I speak as the highest poster upon this quiz, having been with it since inception, and having made no less than 11,419 of the 51,030 postings that have been made on it so far.
