Sometimes, in the comments, you are asked the same question by two (and more) people, therefore, in order for the answer to reach both, you need to write the answer to both of them, which cannot but strain. You can solve this problem, for example, by ticking, clicked a couple of times, wrote once, and the answer comes both. Thus, it is possible not only to inform you about the answer, but also to make it clear that my answer, which is the devil knows where (ie, not questionable), relates to a question, which also do not understand where.

I wonder if there is a similar comment system somewhere?
