Why is it that when I want to mention in a comment or an answer a user, sometimes it displays the name, and other it just doesn't? I'm not sure if that is supposed to happen? Is it because some of them have a space in their user names? Why?

    Can you give us an example where the user name is not shown?

    The @ sign has no special meaning in answers, only in comments, and subject to constraints. Aug 9, 2013 at 13:55

    You mean in your comment to Derick's answer? There the message will always go to the author of the answer. So no @reply is necessary. It would become available (afaik) if another user were to comment on the same post.

  • Your question is surprisingly lacking in free hand circles.

  • So yes, the author of the post will always be notified of the comment. The @reply is not necessary in that case.

  • For the linked duplicate How do comment @replies work?, see a possible answer to your question in item #10: "If only you and the author have been commenting on the post so far, the @name will be automatically removed from the beginning of the comment..."`
