There is a question that is marked as a duplicate and my opinion is that it is not.
I would like to ask how can I point it out? Should I flag it for moderator's attention and say my opinion or should I do something else?
At the moment I have written a comment but most people (if not all) that have marked the question won't be able to see it. That will only happen if by any chance they visit the question again, which is highly unlikely.
