Currently, an author of a question can delete his own question or "vote" for closing.
Sometimes it happens to me that I ask a question and then I realise I was doing some silly mistake.
When this happens, I normally then edit the question and explain the error. For example, in this question I explain that the
hitcount parameter in iptable counts the number of connection attempts, not the individual password attempts.
Still I don't want to delete the question. This error can happens to other people, so while I don't need any more answers to the question, also I don't want to close it.
Currently I am forced to "vote" to close it, and give some nonsense reason for closing it.
I propose that for question authors there could be a more direct "close" action that closes the question directly, or at least that this is implemented for recent or no answers own questions.
