When a OP has one of their questions closed one of the main desirable outcomes is for the OP to edit the question to address the issues that led to the closure. However, where should we draw the line between editing an existing question and asking a new question?
In this case
I think that the edits would be more appropriate for a new question as they completely changed the question. This means that the answers (including mine) which were valid answers to the original question now are not even remotely addressing the edited question.
If another user had made these edits then I would simply roll back the edits, but since the OP made the edits I am hesitant and considering deleting my answer instead. But I find that I am rather irritated by the whole situation since deleting a valid answer to the original question will cost me points.
I think that the best course would be for the OP to ask a new question, but what is the actual policy? Shall I roll back the question or delete my now off topic answer?
