How do I tag/mention users on the forums? So they get a notification about my post (replies etc.)? People keep mentioning me when they answer but when I try the s-code (user=someone) the link looks different so I don't know whether it works. And when I use @ username (no space) there's no link so again I don't know if it works...

The @ username is working (I pinged myself), the link just doesn't always show up. If you refresh the page the link will show up.

The user=someone code does create a link, but it doesn't ping the person to the thread.

Ah, got it. thanks!
