Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Sometimes (quite often) persons write the wrong @name in a comment. For example, in Generic T get type from class Preet Sangha tried to reply me in a comment to the question, but addressed the comment to @xantos instead of @xanatos. Would it be possible to issue a warning when you write a comment that won't notify anyone in the page? (I know there are some rules for matching usernames.)

Very much related: Tell the user who will be notified of a comment. – Hendrik Vogt Sep 10 '11 at 14:43

The other suggestion doesn't seem to directly cover wrongly typed @name. If one speed-write the comment, it could miss it. – xanatos Sep 10 '11 at 16:49
The matching algorithm uses the first three letters of the name, by design. So your "incorrect" example would still match. – Robert Harvey Sep 10 '11 at 19:10
@Robertt: No, that's not correct. See the last sentence in #3 of How do comment @replies work?. (And I can't submit this comment without a backtick, isn't that crazy :-)) – Hendrik Vogt Sep 10 '11 at 20:03
@Robert: Ping!! – Hendrik Vogt Sep 10 '11 at 20:03
Only now I see that Robert provided an excellent argument why xanatos has a good point here :-) – Hendrik Vogt Sep 10 '11 at 20:24
@Robert I know I didn't receive the comment in the inbox. Had I received the comment, I wouldn't have done this question on meta. Ah... Now I comprehend what Hendrik did :-) :-) – xanatos Sep 10 '11 at 20:30
@Hendrik: Aw, hell. You really expect me to read all that? :/ OK, this gets an upvote from me. – Robert Harvey Sep 10 '11 at 20:57
@Robert: No, I don't :-) Just wanted to point you to the standard reference that has become almost unreadable indeed. – Hendrik Vogt Sep 11 '11 at 6:04
