Why we can't comment or report old answers in This actually a question for moderators or any user that can give proper information. I am not a very active user of just answered some question in a period. I can't remember if this was possible before, but currently, I just realized that I can't write a comment in both answer and question. The problem is that I've seen many answers that are wrong or simply useless. I don't know why to keep such low-quality responses. I am also including my own, as I would like to know if an old answer of mine was maybe wrong, so a user may report and I can fix it. I know many people don't take the site seriously, but I would like more resources here in that would guarantee better answers and even better questions.

Thank you if you read it all. I am not a native English speaker, so sorry about my grammar, I know I have much to improve in English.
