You can tag, or mention, another person by using the '@' symbol and their username in the discussion box.
Within your selected group, find the "Discussion" section! In the discussion section, write a message and mention the person you want to notify by using @ + their username.
You will notice that many usernames appear for general names - be as specific as possible to find the correct person.
Finally, press "Enter" on your keyboard to post the message to the discussion.
You can then see the message on the discussion board and a link to the person's account that you mentioned.
