You can reference another user using their name, and optionally by linking to a relevant question or answer that they wrote, or to their profile page (probably not useful/helpful).
This isn't the same as the @ reply used in comments, which actually isn't a reference to a user, but a reply to them. See How do comment @replies work? for more information about ...
Since this is about me, I will answer.
Is there a ping etiquette?
Not that I know of.
Ping etiquette should follow what would be socially acceptable in real life situations. If you would jump into a conversation in real life, you should feel free to do so in comments. I believe comments are fair game.
Bonus question: if A and C are having an ...
After experimentation within this question the current behaviour* has been found to be as follows:
If at any point @yourname was in a comment you will get a notification in your inbox.
But you will only get a red(1) notification if @yourname is currently in the comment (either originally or by edit), i.e. if @yourname is edited out and you haven't seen ...
I want to reply to the mod commenting on it after deletion. How can I do this?
Mods can comment on deleted posts so that they can explain why the post was deleted or otherwise assist the author in better using the site.
If a moderator comments on a post either after deletion or immediately before, consider it a courtesy and pay attention to the ...
For the sake of documenting the official response for later visitors, the reasoning behind the decline appears to be Jeff's comment on Pekka's answer:
there's no valid case for "I need to notify a large number of people" -- at least not one I will support by writing software for it. – Jeff Atwood♦
By "large number of people" Jeff apparently means 3+, as ...
To quote two specific bullet points from the "How do the names get matched?" section of the FAQ you linked:
Matching is performed in reverse chronological order, so if five people named John are participating, @john will match the most recent John. (Use the next rule to differentiate.)
Spaces are removed from the display names for matching ...
After a recent change, the autocomplete feature suggests your name immediately when typing just the @ at symbol:
because your name starts with a non-ASCII character.
If I then add charaters, other auto-completes are suggested instead:
When you comment on a post (question or answer) the poster (asker or answerer) is always pinged automatically. Therefore there is no assistance needed to include their name in order for them to be alerted to your comment.
For more about how pinging works see How do comment @replies work?.
I trust the now deleted comment of @Catija posted to this answer
Probably only one user got notified.
That comment is from mid '10. That question and Jeff's answer is from early '12. It's probable that the check for multiple pings in a comment didn't exist yet. From Jeff's answer:
Bear in mind this was specifically added because people complained "but I can type as many @usernames as I want in a comment, clearly it ...
This whole do not ping me affair is new to me, to be honest. However, I have recently seen a few occurrences of this matter, (roughly) declined in two categories:
The user does not wish to be pinged because the flashing UI causes them discomfort or otherwise breaks their concentration. In that situation, recommendations were made to employ user scripts in ...
Having handled ... a lot of flags and comments over the past few days, I suspect that its a disconnect with how folks see comments to be used.
Comments are, especially now, used as ersatz discussion boards by some folks, and they get a bit attached and grouchy about them being deleted.
Comments are also by design transient artifacts supposed to be used ...
Yes, it is really hard to type the username in comment box in Stack Exchange app. However showing username in a auto-complete dropdown menu is good for web-view whereas in app it may not look good(because no-where in app they used auto-complete dropdown).
Here is simple free-hand sketch of its look
Instead can we have add Reply option within Comment ...
I'm wondering about the reliability of the feature that allows to
address other users in comments using the @user syntax.
"Wondering" means you don't really know enough about it to propose it's wrong or could be improved.
You really should do some reading and once you know more about the system you will be able to identify problems and think of possible ...
You can respond to a user who edited your post using the @reply syntax. Quoting from How do comment @replies work?:
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
It just doesn't include their name in ...
You probably tried to ping the author of that answer. That is superfluous - the author always gets notified if somebody posts a comment on his/her answer.
You can try this with my answer (as long as nobody else comments on it).
Comment replies are meant to notify the user you reply to.
To limit this being used for spamming everyone, comment replies only work for a limited set of people; only those that already are part of the conversation (users that have replied, the author, editors to the post) can be replied to in this manner.
This means that the chances for any conflicts ...
If you want to cite a user's comment, I've found its best to type their user name and then make this a link to their comment.
Get the URL for the link by clicking on the time next to their comment, as documented here.
Starting with the next build (rev. 2014.7.9.2360 here on meta, 2014.7.9.1696 elsewhere), we will ignore multiple periods at the end of a user mention when determining whether a notification should be generated.
Before adding a gravatar, you need to request a feature that actually will allow you to select the specific user you want to ping.
The way the system is designed at the moment, you can't select a specific user, so it won't matter which name you pick from the pop-up. Clicking in the dropdown will only ping the Gilles that commented last regardless of the ...
I did what I always do to answers like this, and lost track of myself.
The short answer is down there, in bold.
Obligatory Philosophical Rant
I think this is a great question, and I don't know why it's being down-voted. It speaks to the actual goal of these sites--getting people help from experts. If an expert answers you, then doesn't follow up with an ...
I highly recommend going to the "chat room" of the site where you posted your question. People who answer a lot of questions are frequently in there. You may or may not find the person who answered your question, but you can almost always find someone who'll help you decide how to proceed. I've been in your situation and a kind person in the chat room ...
The way this works is, if you're solely responsible for an action on a post, you're pingable.
If you create the post, you're pingable
If you leave a comment, you're pingable
If you edit the post, you're pingable
If you rollback, you're pingable
If you edit the list of duplicate targets, you're pingable
If you alone caused the post to be closed, reopened, ...
As a moderator, I would love to have fewer comment flag that require me to figure out all the context. "No longer needed" flags don't tell me why it's no longer needed, so if it's not obvious, I have to review 37 comments and 6 edits (or whatever) to try to understand the situation. That's way too much work.
As a moderator I have, unfortunately, seen ...
[Note: This is an answer to the generic question as stated. It does not apply to the concrete situation which has been described in detail in another answer.]
This particular case is easy:
A: [...] Do X and don't do Y again.
A: I already told you not to do Y.
Asking people to do something is fine, commanding them to do something is unfriendly. ...
As far as I can tell, Jeff, who created Stack Overflow from scratch, was fanatic about protecting the users from unnecessary notifications and emails. For him, and for many others, too many notifications and/or emails would be distracting and disruptive. No personal messages, no instant emails.
I believe this is the reason behind not allowing more than one ...
