To tag a forum member, just type the @ symbol on your keyboard and start writing their name. You'll be shown a drop down box of forum members whom have a matching name. Just hit return when the member you want to mention is highlighted. When you submit your post, they'll receive a notification to have a look.
This works for posts and comments too. 😊
