1. Go to the 'Label' tab in the 'Browse Space' view of the space.
   
   
2. Click on the link 'popular labels'. This will list the most popular labels in the space and also display a link to view all 'global popular labels' (across the site).
   
   
   • Clicking on a label will display all content in the site with that label.
   • Click 'global popular labels' to view the most popular labels in the site.

In both these views, you have the option to sort the listing of labels to display them 'alphabetically' or in order of their 'popularity'.

The bigger the font size, the more popular the label.
