I know that for commenting on a certain question asked by some other person, one must have a minimum reputation of 50. Recently, while reviewing late answers, I came across a situation where a person without the privilege of writing comments wanted to ask something, and he wrote a comment in the answer section.
My question is what should be done in such a situation. Should he be allowed to ask something in answer, which I don't think should. Or should he wait and gain some reputation before he can post a comment.
