Thank you
@Airborne101st45 for posting.
As air said, you can type @username to tag someone in a message. Next time they view the forums, they will see a nice little message in their bar along the top, very much like when you get a message, except this shows under "Profile".
When clicking on this, you get a display of all the messages you've been mentioned in in the last 3 months (this might change) and a link to them, along with who mentioned you.
And as expected, your mention is in there. You can also click on some body's @mention to view their profile.
If @Akomine wants to make this better, feel free. He is better at PSAs!
@TheCatsMangler because he doesn't have anyone else to try it on.
It doesn't work on yourself
