Mention user on a comment

[t-jibaut]

Hello, 

I'm new on SAS VA and I was wandering if that was possible to mention a specific user on a comment (based on a report or object) ? 
I've tried to use @ as usual on most website sites (including this forum) but this doesn't seem to be working.

Does anyone have an idea about this possibility ? 

Thanks and have a great day !

Thomas
