We get a lot of perfectly reasonable questions asked as answers to questions.
I'll often reply and tell the person how to ask the question the proper way on this site, but it's rare that they ever do. More than likely, it just gets deleted by a moderator.
It'd be possible for someone else to ask the question on their behalf, but I'd really like to see a way for moderators to be able to directly promote an exiting answer (maybe even comments) into a full-blown question ... maybe add a link back to the original page that they posted it on, in case it was a follow-up.
So what would it take to get that functionality added?
