Thanks, Steve
I hadn't asked any questions for a long time, just answered them, so I never saw the "best answer button" until it showed up on your reply.

The FAQ is still being worked on - for now, suffice it to say we've implemented Top Answerers and Badges to improve overall community quality, as we elevate the really good comments to the top of the thread via "Best Answers".
