Many thanks for this post, Figure.
I do feel slightly frustrated with the lack of feedback from some questioners. That's not because I'm seeking praise (although it's always welcome!) but simply because I'd like the chance to provide additional information if my original post didn't completely 'hit the mark'.
Since we're handing out praise, can I mention a few people whom I particularly respect on AB?
You've mentioned ACtheTroll. My only complaint about him (or her?)is the totally inappropriate choice of screen name. 'Troll' is often taken to mean someone who posts abusive, argumentative and unhelpful posts. AC is exactly the opposite! ;-)
Vehelpfulguy, Fo3nix and Ethel are also among my 'star contributors', as is Clanad (and many others whom I'd remember if I wasn't half-way through the final can tonight!) but my real 'hero', on AB, is the wonderful Dzug. I often post long-winded answers, spreading across several posts, whereas Dzug has mastered the art of prec�s and provides exactly the same information (or better) in a few short sentences.
