Both groups, items and links are assigned labels when they are created in a buzPAK. The default label assigned to a group or item is the URL (web address) of the website or webpage associated with the group or item. The default labels for links are the names of the buzPAKs the link is attached to. Labels can be shown or hidden in a buzPAK, and you can edit labels if you want them to display something other than a URL.
