Suppose you had a question, and you really want a good answer that would solve your problem, but noticed it was already asked by someone else. However, no one has posted any answers. The question is technically considered "unanswered", but a lot of users who would otherwise bother to give a correct answer probably skip the question completely for some reason.
What should I do in this case?
One idea is to ask a new, completely identical question, in the hope users will notice the new question and post an answer there. But would that go against SE policy?
Note: This is adapted from If you are not satisfied with answers on someone else's question, should you ask your own?, but that doesn't cover the case where the original question is unanswered. Also, it is not a duplicate of How do I get attention for one of my own questions without a good answer?, as that question asks about getting attention for one's own questions, while this one and the one linked above ask about getting an answer if someone else has already posted the same thing.
