Earlier Mamya suggested:
I may be alone in this but if someone asks say 3 or 4 crossword clues, I click to reply and of course the question is no longer visible, trying to recall the numbers and letter counts becomes a memory test.
I have had terrible trouble with this but have solved it by copying and pasting the question into the reply box and editing out what I don't need before adding my reply.
It would be useful to have the original question on the screen but often questions are added to a thread as it grows so the question may not be the first posting on the list.
