Lets say an user "John Doe" commented under some answer post. How to write a comment that will contain a referral to John Doe's username? (referral by using the @ symbol). I've tried:

@(John Doe)



Unfortunately none of them worked for some reason.


@autocompleting was implemented some time ago for comments. You should be able to type @ followed by the first character of the username and you'll be presented with a list of suitable usernames to tab through.

@autocomplete in action

In the example above BillWeiss real username is Bill Weiss so just removing the space(s) should also work.

  • Should the autocompletion work when I reply to an user answer and I refer to the user, who posted the answer? i.e. here: superuser.com/questions/401933/… – colemik Mar 18 '12 at 11:10

    Comments to answers are automatically notified to the person who wrote the answer to @'s are not needed. – user9517 Mar 18 '12 at 11:20
  • Thank you lain, you're right. Why would I use the @ syntax if I can just write the user's username by hand. I've overthought that... or maybe not. What do you think about if the syntax would work in this case also? My thoughts: typing the username through @ is faster than doing it manually and the auto completion ensures that I won't make a typo in the username. Also, I think it's more pleasant for the receiver if he/she sees his/her username in the answer / comment. – colemik Mar 18 '12 at 11:35
