Users such as T J cannot be mentioned in chat.
Replies work :(TJ_message_id) reply, but simple mentions @TJ do not.

There is no ping, hovering on the message has no effect when it should highlight the last message of mentioned user, and there is no on-site notification.

Screenshot of TJ's mention

This might be linked to the fact that mentions with 2 characters simply don't work. Trying to mention someone named foobar with @fo will not work even if there is no ambiguity in who the mention is aimed at (there is no other user in the room whose name starts with fo).

    What if users change their name on purpose so that they can't be pinged? :P Commented May 17, 2016 at 9:27

    Can confirm. I'm a floating smiley, and even I can't ping those users. Commented May 17, 2016 at 11:43

    @NikolasCharalambidis I think people are free to be not pingable, and it's reasonable to not allow 2-letter pings (due to ambiguity). We just need a clear warning that you'll lose pinging privileges with a short username. Commented May 17, 2016 at 15:55

    This was reported on mSE several years ago - no response though: Chat not pinging when name is too short Commented May 17, 2016 at 20:59

    @Kyll I beg to differ. The behaviour you're describing corresponds to comments on the main site, but chat is different: everybody who matches will be pinged. Compare this screenshot courtesy of Ander Biguri with the transcript around here: both Ander and I were pinged by @​And. Commented May 18, 2016 at 16:15

Fixed: as of now, users whose normalized name consists of just two characters can be pinged in chat.

    @Tunaki The target for that one is at most 26 users, so how about no ;-) Commented Jun 2, 2016 at 13:18
