Hi Paul,
Yes, I am the self-appointed keeper of the word lists, otherwise anyone who wishes to can update them.
Re the clue - I don't think it needs a 'short' as A is in Chambers as an abbreviation for 'American' in the sense that we accept L for 'left', etc,
however, I agree that the wordplay would work better for a word starting with A, rather than A being part of the anagram fodder.
