Consider this scenario. I run into an issue and put together a detailed question. I get a few answers but no luck. It turns out it was a complete red herring, and it was a completely separate unrelated problem that was causing the symptom that was in the quesiton.
So given that the question is not really relevant. In these cases, I would go and delete the question given that it's not a valid question. My concern is that I would like to notify people that were looking into it instead of simply removing it under the covers to avoid anyone wasting time trying to help answer.
What's the protocol here? Should I put a vote to close my question? Is this not a good use of "delete" for questions?
