Someone edited a question of mine, and I asked that person a question by leaving a comment on my question. However, when I typed @username_of_editor, I noticed SE did not offer the username autofill that it normally does, so I suspect the user will not get a notification of my comment. In addition, I noticed my question did not jump to the top of the active list after I left the comment, so that user may not realize I have left a comment for him.

Editors can be notified but their names are not available for auto-completion; it'd take too much resources to have to query the database for those names.

If you matched their name (even partially) editors will be notified, yes.

Quoting from How do comment @replies work?

  • Tab name completion can be used, and that knows when @name is unnecessary and will then not automatically complete names. It also does not work for editors.


  • Notifications apply to the author, users with active bounties, commenters (associated to current non-deleted comments), and editors of the question or answer that you are commenting on—users not in that list cannot be notified. [...]

Emphasis mine.

  • Want to clarify why you said an editor can be notified. Will the editor be notified if you do an @editor? Jun 29, 2014 at 23:01
  • @pacoverflow: yes, they will be notified. Jun 29, 2014 at 23:02
  • Thanks, I hope it still works considering he has a space in his username. I did an @Firstname Lastname Jun 29, 2014 at 23:06

    @pacoverflow: see the referenced FAQ; it'll work but the correct full version is to use no spaces; @FirstnameLastname. Jun 29, 2014 at 23:08
