I'd like an option to close or delete a question that I asked by this motivation:
"The matter was resolved by other means than following the answers. "
Or similar rationale. Since sometimes the answers are good and there can be 2 answers to a question and the problem in the question was resolved not by doing what the answers suggest but by some other activity that solved the problem.
Or is what should be done in these cases, is answering your own question?
