# Notification via @(user name) not working

After changing my user name to D B Lim, it seems whenever someone does @D or @D B Lim, I don't get a notification. Is this some kind of glitch? Should I change my username to one that is just one word?

Thanks.

• To help with the diagnostics: did Srivatsan's comment here reach you or not? Note that @D definitely doesn't work, as three characters from the username are at least required. – J. M. is a poor mathematician Sep 5 '11 at 12:15
• @J.M. No it did not work. – user5783 Sep 5 '11 at 13:07
• @DB: There's an exception if there are spaces in your user name. I just tested that one can notify you with @DB, although this has only 2 characters. – Hendrik Vogt Sep 5 '11 at 15:16

You need to remove the spaces to get the notification working if the first part of your username is only one letter, so @dbl or @dblim should work.

See How do comment @replies work? for much more details about the comment notifications.

• Personally, I find it quite confusing when I find names that had spaces or dots in between. This post seems very useful. Thanks! – Srivatsan Sep 5 '11 at 15:00
• It is interesting to note that @DB (or @db) also works. – Hendrik Vogt Sep 5 '11 at 15:15
• @Srivatsan: You may want to have a look at this userscript or that one – t.b. Sep 5 '11 at 15:35
• @Theo Wow, that should be really useful. Thanks! (A separate thanks for pointing me to stackapps. I hadn't known about this...) – Srivatsan Sep 5 '11 at 15:39
• @Hen Do those two-char names work per doc or per actual confirmed use? – Bill Dubuque Sep 6 '11 at 5:54
• @Bill: Well, you know what "documentation" means here - most of it is written by the community itself, after actual confirmed use. However, in this case it's documented in an answer by a developer, namely balpha. (That @DB will work is not really documented there; this I tested myself.) – Hendrik Vogt Sep 6 '11 at 7:46

• @DB, I can confirm what Bill wrote: if no @ syntax is used, then you'll only be notified of comments to your posts, and this is Jeff's post. Thus, I used @DB to notify you of this comment, and it only works because you already participated in the comments here. Bill in his first comment had no way of notifying you. – Hendrik Vogt Sep 6 '11 at 11:07
