Favorites can be shared via email. Just go into your Favorites, via the main menu and click on the email icon. 

You can also add Favorites to a Playlist for more sharing options. 

Playlists, like Favorites, can be shared via email. 

You also have the option of copying the link to your Playlist, as can be seen below, and adding the link in your Blackboard site as a sharing option. 

From the Playlist area, you can also create folders to better organize your playlists. This may be helpful for group work and for creating playlists for various classes.
