Factor 30 you kindly keep redirecting people back to sites where questions have been asked previously, but unfortunately not answered, or at least not correctly. So naturally the same people try again, hoping they might find someone who may have missed the original question and who doesn't spend all their time trawling all the way back through the old questions.
I'm not going to trawl through the threads for them. They are looking for answer so I'm pointing to where the answer might be, but thanks for doing it.
Unfortunately there's no easy way of knowing whether threads contain the answer or not. More often than not- especially with crosswords- the answers can be found that way.
I'll continue to kindly help posters in this way unless the original poster says "I've seen this asked before but no-one has answered it yet"
