Well, I finally figured it out.
"Bartok Fan" likes "Bluebeard's Castle" (a very dark Opera by Bartok) and the poster "It's all Dark" is a fan too.
"Bartok fan" does not want to post about equipment until the argument is settled about which production company did the best job with the Opera.
AM I RIGHT?
(Otherwise I haven't a clue as to what is going on).
