Thank you, Prof M, much appreciated.
I recognize that over recent years many of the barred puzzle aficionados have transferred their allegiance to a different forum. It isn't my intention to provoke debate by drumming out my views about accuracy of clueing on a site where there is a general acceptance of the looser clueing usually found in more libertarian puzzles, so I shall confine my posts to the other forum in future. My 15 Best Answers in five years of trying suggest that my absence won't be felt too severely :-)
