You can tag other users by simply using @ followed by their username. When typing in a username, you will see a dropdown option showing usernames. Clicking on one of these will complete the tagged username in the post. Alternatively, just type in the full username. Although you will need to spell the username correctly, you don't need to worry about capital letters as these will be added automatically when the post is made. Tagging can be used in forum posts, profile posts and profile post comments. Tagged members will receive a forum alert and also an email if enabled. Email alerts are on by default but can be disabled in Contact Details. Tagged names in posts will be hyperlinked and clicking on this will open up their Member Card.
