There are numerous examples of questions on TeX.SX and SX sites where the OP has asked a question, some one has provided at least one complete solution but the OP has not accepted any of the answers.
Question Is it possible for a moderator to accept an answer for the OP in such cases? Alternatively, should it possible for the community to vote that a particular answer to a question be marked as correct when the question is "abandoned" by the OP?
My question is motivated by #244645, which is exactly of this type. People are currently voting to close this question on the basis of the question being "too broad", and hence implicitly unanswerable. This is wrong, however, because the question is easy to answer and some has done exactly this. The "correct" thing to do would be to give the person who answered the question (in this case Harish Kumar), credit for what they have done.
