If you answered a question, and a posteriori, your answer is not relevant to the question because the question was edited to a different question?
Is there a possibility for someone who asks a question to modify it to another topic, e.g. a question about lulav changed to a question about matsa?
I ask this because I noticed that this post I tried to answer yesterday is today another question.
Is there a policy to prohibit some edits of the question that can lead to a lack of coherence with answers already existing. It seems that if I wrote a question and people answered, I can further change the question without problem.
