When replying to a user in a comment, their name is automatically suggested in a pop-up:    But that only works if they have already left a comment.  Sometimes I want to notify a user who has made a , but there no pop-up that suggests the name of these users:    Does the user still get a notification of the comment if you manually type in their username?  Edit I have changed this to a feature request, instead of posting a new question. Is this OK?

@username auto-completion for comments was , and is already active on MSO.  However, it only seems to auto-complete the usernames of people who have commented on the post. According to , the list of users who can be explicitly notified also includes:   Anyone who edited the post Anyone who started a bounty on the question The &diams; moderator or  who cast a binding close vote on the question   Why not auto-complete those, as well?

It would be nice if the @username autocomplete idea for comments could be extended to answer posts. Although, what I'd really like to see is a faster way to reference other people's answers to a given question, within your own answer. Say user 'foo' already posted an answer. I would like to provide a link/credit to foo's answer within my own answer. As it is right now, the only way (that I know of) to do this is by copying the link to their answer and creating a link within my answer. It would be a small time-saver if the @username notation could be used to do this instead, such that @foo would be automatically expanded to a link to foo's first answer in the current question.

Currently, a user does not get any notification when a trivial edit (less than 6 characters, by a user who has the ) is made on one of his/her posts. As in .  Even though the user is trust-worthy (owing to the rep of the user), wouldn't it be nice for the OP to get a notification whenever an edit is made, even trivial?

User who cast a binding close vote on a question should be notified when someone comment-reply him/her, even without ever leaving a comment.  This still works fine when I am the only close voter, e.g.  (tried with my sock and deleted the comment already), however this fails to work when I'm not the only close voter, e.g. .  Tested both with a sock account and with the help of another user - no notification.  I noticed it yesterday and hoped it was a temp glitch, but then today I saw by chance , which is important for me to be notified about, since I can reopen the question with single vote.  Just to prove, a screenshot: (click to enlarge, don't want to clutter)        Can this please be fixed?

When the owner of a question comments on their question or an answer to their question or self-answers their question, they get a special color for the box around their username.  The problem is, you can't see the box:        Can you please make this not white on white?

are described at length, but don't address bounties.   If I put a bounty on someone else's question, will I be notified of undirected comments? Can people notify me via @-replies even if my only involvement with the question is putting a bounty on it?   If the answer to one or both is no, could we get a new feature putting anyone with a bounty on a question on par with the question's author for the purposes of comment @-replies?  Or, if not, at least add them to the list of @-reply targets to allow messaging them?  This was all prompted by  from DanQ that had a bounty put on it by rabidsnail, presumably because she had the same problem.  Once it showed up on the Featured Questions list, people asked for more information in comments.  DanQ never responded, and may well not have cared about the question by that point.  Presumably rabidsnail cared, but did she get any notification about the comments requesting more info?  (I assume rabidsnail checked in on the question at some point, and obviously didn't add more info then, but maybe she would have had she known sooner.)  There's also the question of proper etiquette when elaborating on a question that's not yours, but that's beyond the scope of this question.

I have a situation where different users have asked questions and I answered them. The problem is not that they haven't accepted the answer which can tell me that it is correct or not. But they are actually not responsive and it seems to me that answer is being ignored. Or they asked the question just for the sake of asking.  See -the user was last seen yesterday, the same day it was answered.  -the user was last seen today.   which is also upvoted by a fellow user, but the OP is seen till days after it was answered and is not even commenting.  I went through a lot of question on meta on similar situation such as  where Anna says that it is completely voluntary for users to accept it.   But then again, I believe it is becoming a fashion, to ask a question read the answer as a suggestion and leave it.  It is discouraging me. I am not saying that my answers or suggestions are 100 percent working but I atleast need be told so I can improve it. And more importantly I am not the only one facing this.  Please advise.  EDIT : Well, I got a lot of suggestions from the answers and comments combined below and I have to say that I agree with what Cody Gray has to say and just keep on answering the questions, the returns(good or bad) may be now,later or never and just move on. However, in my own defence I would also say that I did not raised this question to pin point any user but a bad practice that I find worthy of discussing. Thanks.

How do the comment replies (aka &quot;pinging users&quot;) work?  Who can I send an @reply to? How do I respond to a specific user when entering my comment? Will they be notified? What do people mean when they talk about &quot;pinging&quot; another user?  Related:

I asked a question on SO and someone gave me the answer as a comment to the question. Subsequently, someone else gave the same answer as an answer.  I would like to give credit to the poster who made the comment. Is there any way to do that?   Being new to the site, my only thought would be to contact the commenter and tell him to post an answer if he/she wants credit.

At the moment, I have the latest notification in the global inbox, content of which does not correspond either to the comment itself or the copy of it on "recent responses" page. This seems like the comment was edited and the updated version was not copied to the global inbox.    ETA: OK, now this looks more coherent.

If you use an @notification in chat messages it will notify the corresponding user with a small circle (or snowman) on their gravatar and (if enabled) a sound effect.   Now, when you have notified a user that way they will be notified again if you edit the message containing the @notification. I don't think this behaviour is optimal. In most cases I don't really want to ping the user again; I just want to correct some small typo.  I suggest to change the behaviour to not repeat the ping when posts are edited.

I just saw a user named: .yahoo.co.jpaqwsykcj3aulh3h1k0cy6nzs3isj  Could new users be named according to their user-number, or something other than "Unknown"? Perhaps User1234567 instead? It would be less awkward to address them in answers and comments.   Additionally, I often times have to check profiles to make sure users aren't abusing the system, since I find many of the same questions from "unknown (google)" from time to time. That, or I'll mistakenly think I've helped the user on a similar issue in the past, and assume the user has knowledge that he or she does not have.

At the moment normal users do not get notified if someone suggests an edit on their own question or answer. I'm not even sure if they can see these suggestions if the do not have the corresponding privilege.  I think users should get notified about pending suggested edits on their own posts and also be able to see and accept or reject the suggestion independent from their own reputation.

It appears that the error notifications about comments in Mobile Stack Exchange do not work (in-browser mobile site), on many stacks. Something should be done, do we report bugs here?  My original problem was that I've tried to post comments on answers for various boards, and the button wouldn't do anything, no error message or anything. I recently found out that it's because I don't have enough reputation points, but there was no note explaining the rule like in the desktop version. A couple boards I tried it on are the User Experience one and StackOverflow.  Also, user Mooseman is eating pizza claims the same about "your message is not long enough" error.

Is there some way to contact another user by using their name in chat, so that they get notified?  It seems that when discussion starts in a comment thread, it is easiest, instead of migrating the entire set of comments, just to start talking about the topic in chat. But to get someone to go there, one continues in the comment thread to say 'hey, let's go to chat'.  Using @ThePersonsNameYouWantToChatWith in chat doesn't seem to give them a notification; how can one notify them that you are said something in chat to them?

The fact that a user can change their name at will can lead to some confusion in the comments.  For instance, suppose a user named "foo" changes his name to "bar", all those comments signed by "foo" are now signed by "bar", but responses to "bar"'s comments still start with "@foo".  Could those "@foo" references in comments be changed to "@bar"?    A brief discussion on this has set me straight.  I didn't think it through.  Request withdrawn.

I just received the following in my Response pane (from ), but you can see it was meant for another user.  The @Robert line seems to have found 'Robert' in my name first, instead of Robert C. Cartaino.  I think the comment notification feature should match based on the closest match from the first character in a name (in posting order), and not just the first match found in posting order.
