I've just been asked for a list of answers to confirm or disagree with current flags. I disagreed with the current flags in one case and said so in the answer box. Now I see, that I've misread the question and that flagged answer and my "said-so" is wrong. However when I tried to re-flag, the system dismissed this, saying "you've already flagged". My correction should go to the moderators that he/she can delete/remove/ignore my comment. How can do that by flagging (?) or just here-and-now by this question?
