Yes, I support any positive attempt to improve things. I have often thought the best thing is not to answer any poster who cannot be bothered to give the number of letters - or even the clue in some cases! But someone always comes along and gives them the answer. Drat! If we could get those people not to respond...
Re letters filled in, there will of course be some people posting clue and letter number who will not have filled in any letters so we should bear that in mind and respond politely.
