I'd really like to keep my 100% accept rate. But one question I asked has a great suggestion in the comments, but the answer supplied misreads the question, as the author admits in the comments.
The way around this I can see is to use the useful comment to do the work myself to find an answer, then answer my own question, and then click to accept that as the answer.
Is that the correct way? What if I cannot usefully answer my own question. Does the presence of an incorrect answer doom me to a less-than-100% accept rate?
