Dutch_122 is indeed a frequent member on the BA and QR fora, and many of us here regard him as a friend.
He also happens to be an absolute whizz when it comes to flight bookings, and has helped many FTers (myself included) with complicated itineraries.
Glad he was able to sort you out with your booking, and I'm sure you'll buy him a drink when you're next around AMS!

P.S. It might be worth adding, that he isn't BA staff - albeit he knows their systems exceptionally well.
