@Dutchy,
1. the person posing the question has to choose "question" v "discussion" when they start the thread.
2. I would guess the answer will be no, since the question/discussion formats haven't been around for long - and that's what creates the number - I can't imagine any of the volunteer staff has the time or energy to manually poke through old threads to look at questions anyone might have answered (and they wouldn't be able to identify the 'best' answer in any case)
3. the person asking the question - having chosen the question format - will see the option to select any following post as the best answer - as I recall there was a button at the top of each response visible only to the questioner - visible only until they've selected the 'best' answer.

Have you tried asking a question? It's really the only way to see how it works.
I'm not on the Support Team - just a poster and poker.
