I love this site for the intelligent help and erudite answers, but I hate to see it degenerating into squabbles and nastiness. It is good manners to thank someone if they have helped you, but sometimes it doesn't happen for various reasons. I always try to thank people who have helped me as i appreciate that they have taken the time and trouble to assist me. However there seem to be one or two people who take a failure to acknowledge as a personal snub, which is silly. Can't we please get back to the spirit of this site which normally makes it such a pleasure to use? And can those people who have fallen out please kiss and make up?
