I'm pretty sure you click on their name, and in the list there should be an "add to buddy list" thing you can click on.
Click on their username and scroll down until you see the 'Add to Buddy List' button. It should be right below the 'PM this person' button.
Quote:A buddy list is a list of friends that is set up so you can access their messaging, home page, and when they were last on easier.
