What should I do when I see a question that is a duplicate of another one?
- Should I answer it?
- Should I downvote it?
- Should I comment?
- Should I edit the question to indicate it's a duplicate?
- If I can, should I (vote to) close the question?
- What happens when I vote to close as duplicate?
Or: Why did a comment with my name on it just appear? - Should I flag it for moderator attention?
- What about similar or related questions?
