I hope everyone is off to a great new year. We've added some new features we hope will be useful to you:

1. Tags: Study lists now can be tagged, allowing you to see related lists, related tags, and explore the tag cloud.
   
   
2. Heads: We'll show the number of people who have added the list to their "head" (study lists they want to keep in their head). This helps you see if a list is useful to other people. If you delete a list that others have in their head, or stop sharing the list, then the list will be removed from their head.
