How to tag other members in posts aka using the @mention function
The @ feature allows members to tag a specific member who will then receive a notification that they have been tagged aka 'mentioned' in that post (unless they have @mention notifications turned off). The @mentioned member can then click the notification to take them to that post.
To @mention someone simply type the @ symbol and begin typing the user name, a menu will pop up and the member you want can then be selected.
The finished "mention" will look like this: @DarkStormm and it will be a live link to the member's profile.
Note: For the @mention to work you must select the username from the pop up menu.
