Thanks, that's the best explanation I've had yet. It clears up some of my misunderstandings about it - leaves me more than a little confused over some of the previous postings & comments, even from some MVPs.
I still think it's a little remiss of one of the people involved in awarding the MVP title to get rid of all of the notes on why someone got the reward & does leave the system open to accusations of unfairness.
But as I said, I don't take any notice of the letters after names, it's the content of the answer that is important, not who gave it or what titles they hold.
