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 ...
I've been meaning to make this change for a while, so this was a good nudge to finally do it:
From the next build on, if a comment thread contains a comment by a user whose name starts with a non-ASCII letter, then just typing @ will bring the tab completer up with that name:
If all reply candidates start with "normal" letters (or numbers), then the tab ...
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 ...
I know all has been said. I know I cannot upvote twice. Maybe a picture helps. Below, @ajax333221 was removed, and also that original author is not listed as this a community wiki post:
That bothers me a lot.
Humor is okay, but we're here to solve problems
Well, it's one thing to slip in a casual, yet related, joke to a question about a real, actual programming problem that you're facing, but if the sole purpose of the post is simply to get a rise out of people, then this just isn't the place for that.
I use Stack Overflow a lot in my work. When I land on a ...
Perhaps a mixed solution will suffice in these cases.
My suggestion would be to append the users unique id to the username when auto-completing the @replies - perhaps within brackets. The resulting @reply would appear as the username - but the notification would be sent to the correct user.
To compliment this feature we could also have the user_id ...
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 ...
Flag the question for moderator attention. Explain in detail what's going on. This is something of an odd situation, so you'll want to make sure the moderator responding has enough information.
You could also flag individual comments, as Tim ManishEarth suggests... However, moderators don't see the identity of the person flagging when it comes to comment ...
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 ...
I support this request, but I'd like to suggest a minor modification:
If the the first comments where form John, John Doe, john and john, it might be difficult to figure out which John @john-2 will notify.
I'd prefer the unambiguous @userid.
Looks like you can. This comment notified @JeremyBanks. Interesting functionality, since the autocomplete doesn't work.
Undirected comments have no effect.
Regarding undirected replies, I guess it's the duty of the bounty giver to keep track of it themselves. Remember, there are truckloads of comments on the answers as well--and it's good for the ...
No, it is not. If one appreciates the comment and wants to show it, they can vote it up via the arrow to the left of the comment:
The tooltip even says "this is a great comment".
Putting another comment just to say "your comment" was great is noise and should be flagged as "not constructive / off-topic" or "chatty" (or if you want, something custom, but ...
You forgot option 5:
Flag the comment!
Flagging is the go-to option in cases like these. When something bad is happening – but the system doesn't let you handle it – flag it. Our mods have unicorn powers and can deal with it. Usually. They can delete the comments, send him a mod message (warning of suspension), etc. Use the "other" option in the ...
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 ...
I followed your link to Lawrence's profile and from there to an answer of his. I clicked Add Comment and typed @l whereupon the autocomplete offered me his whole name.
For Ωmega I couldn't find a letter to type that triggered the autocomplete - I expect copy and paste would work.
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 ...
You should start contributing by asking good questions and leaving good answers, as explained in the FAQ. Once you gain enough reputation through your own posts (or by suggesting quality edits to other people's posts) you'll unlock the ability to leave comments.
The gain in having a restriction on commenting is that we don't get spammers and new users (who ...
The reason why that question was closed has nothing to do with its being humorous.
It was closed because it was a crap question with zero specific detail, or previous research.
How does the SO 'council' view such humour!? Is it feigned upon or welcomed?
there is no such council really. Just thousands of monkeys with guns users with enough reputation to ...
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 ...
