Since we have a way to see 'Unanswered' questions now, there are a couple of things that jumped out at me. Not sure if I am missing how to do these or if they need to be added to the future enhancements list:
1) It looks like a lot of people 'Comment' on a Question rather than providing an Answer. This means that there are many questions listed as unanswered where the answer actually lies in a Comment (but noone has submitted a formal Answer). Is there some way to tag a Comment as the Answer?
