That space in the username
John X is potentially complicating matters.
From the unofficial FAQ about the
name is the username with all spaces removed.
- Single trailing punctuation such as a dot, comma or colon is ignored, like
@name, yes works, but
@name... no does not.
There's the further, important, point:
If the first word in the display name is at least three characters
long, then there must be a starts-with, case-insensitive match of at
least three characters in the display name. This means
never match anyone, unless a user uses a first word that is only two
@Jo will notify Jo Miller, but not John, and
will notify B. Gates, but not B.Gates. If there are more than three
@name, then all given characters must match (neither
@aliceinwonderland will match user Alice).
To reply to John X, I'd suggest either
@JohnX:. I like to stick with
, because those make more sense than reading a comment like:
@sarnold. You're silly. Putting the notification at the end works (which is why the
. is allowed) but I find it easier to find comments directed to me if the
@sarnold is right up front.
