Removing a user to your Buddy List can be done in one of two ways. From your main "My Quit" page, go down to the "My Community" section and click on the "Manage Buddies" link. Once you are in the "Buddy Manager", click on the check-box next to their username under the "Remove" column. Then click on the "Update List" button to save the changes. The second way to remove a user from your Buddy List would be to go to their Profile and click the "Remove from my Buddy List" button.
