@Mentions are a great way to get someone's attention or direct other readers to a particular user. When you tag a person with an @mention, they will receive a notification. @Mentions are public and visible to everyone and link to the user's profile.
To tag a person, start typing the name of the person and a suggestion will appear. Select the user you want to tag and the tag will be inserted.
