I want to reference another user in my answer like I do in comments (
@user). How can I do this?
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 comment @ replies.
If your intent is to somehow notify a user that your answer is posted, that's not currently possible. The user who asked the question will be notified that an answer to their question was posted, but you can't specify other users to notify.
As far as replying to another answer: if what you're posting is a response to an answer by another user, it should be a comment on that answer (this will notify the user who posted the answer that they have a comment). You should only post an answer if it is, on its own, an answer to the question. Imagine if all other content on the page were gone and only the question and your response were left. If the page wouldn't make sense, or your response would lose meaning, then it is not an answer.
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.
At this time, a feature like that is not available, for several reasons:
- No feature-request for it has been made.
- Replying to another answer in your own can lead to rot - it's never good to have your content be dependent upon content that you cannot control.
- It could be seen as abused as a way to be malicious to a user, for example:
- User A posts an answer, that is incorrect in some minor case/scenario, and gets 3 upvotes
- User B posts an answer, which points out those flaws, and gets 5 upvotes
- Over time, user A's answer gets downvoted because of the edge case that wasn't handled
- User B profits
That's not the type of behavior we want to encourage on this site - compare to the following real-world scenario:
- Person A begins a speech
- Person B (in audience) interrupts the speech and points out that the speaker mis-pronounced a word, shaming him publicly
- Person A is afraid to ever speak publicly again, for fear of being humiliated
So, essentially, by singling out an answer or a user, you humiliate them in a public fashion. As we are a community that encourages all helpful answers, and the input we can get, we don't need people becoming upset at other users and leaving the site.
Short version of previous answers: you can hack it using a hyperlink to the profile, but they won't be notified about the reference.
