Another (inferior) crossword site has today posted this notice:
“Recently there has been a noticeable increase in off-topic comments on puzzle related posts, many of which would better be posted elsewhere, for example on the General Discussion page, or not at all. Please be circumspect when posting a comment. I do not want to limit input to the site but equally I do not want it to be cluttered up with off-topic asides.”
I would like to point out that off-topic comments are, as ever, welcome on ths friendly site!
