[edit] I Own Boxes

Some users may recall that there were boxes used to indicate they owned various styles. Unfortunately, the features that utilized this preference was never implemented; as such, the boxes have been removed until the preferences get overhauled.

[edit] Friends

To use the friends functionality, you need to select out of the list of all users the ones you're friends with. To multiple select, hold Control on a PC as you click, or Command on a Mac. Alternately, you can click the "Add/Remove DJ as a friend" link on their View User page when you're logged in.

The benefits of selecting friends are:

• Your friends will be highlighted on View Song.
• You can also filter View Song to just show your friends and yourself.
• You will see an average of your friends' scores, as well as the top score, on the score entry page.
• View User has a separate popup to quickly view your friends' profiles.
• DJ Battle also has a quick battle popup.
