Say I ask a question. It then gets marked as a duplicate (possible or exact) by someone commenting so. However, the question is not a duplicate, the person who posted the comment either didn't understand the question or just looked at the title. What would I do to get rid of the box that says "Possible duplicate of (link)" at the top of my question?
3Until the question is marked as duplicate by five people (or one moderator), you as the author are the only one seeing the box. Explain why it's not a duplicate (at least of the linked question; the comment is visible to all), and hope it won't be closed as dupe.– Daniel FischerJun 21, 2013 at 18:04
3Nothing. You would have to hope nobody else votes the same way. Until it's actually closed, only you can see it anyway. And the votes will expire at some point if they don't reach the required 5 votes.– BartJun 21, 2013 at 18:04
6@Bart Editing the question to make it extra clear that it's not a dupe would be a good action to take in the meantime.– Adam Lear StaffModJun 21, 2013 at 18:12
1@AnnaLear Ah, and here I was writing an answer advising the OP to come to Meta, rant and invoke Godwin's law....you sound more reasonable... ;)– BartJun 21, 2013 at 18:13
Unfortunately for you, there is no way to remove that message. But don't worry, only you can see it for now. Until the question actually gets closed as a duplicate, nobody else will see that message. Should nobody cast the same vote, then the close vote will expire at some point, taking the message with it.
As stated by Anna Lear, you can use this opportunity to clarify your question and make it really clear that it's not a duplicate. Don't just say it isn't one, but inform us how it differs.
Should the question then inadvertently get closed as a duplicate, you'll already have prepared your rebuttal. Either the community can vote to reopen it based on your clarifications. (The preferred route. And you can cast the first vote if your rep is >250) Or you could at some point flag it for moderator attention and have them take a look at it. Use the "other" flag option and explain what the situation is and how your question was closed incorrectly.
