On the entire SE network there is a huge number of questions that are unaswered and where the author doesn't use the system anymore, usually is a user that has a score of < 100 and that will not act on any comment added to the question.
I would like to propose a feature for requesting a question takeover, so you can become the author so you can accept one of the existing answers.
Clearly this should not be available on all questions, but it would extremely useful because it would allow people to repair broken stuff.
This will prevent creating almost-identical new questions or other similar problems caused by the lack of interest from the original question author.
What do you think about this?
Look at 4th question, which happens to have a real valid answer but which is still listed like one question that does not have an accepted answer, definitely a sign that probably the answer is not good.
