The "My Favorites" feature lets you bookmark and subscribe to videos and channels you find in Yahoo! Video
You can save a video or channel to your Favorites using either the "Save" or "Add" buttons, respectively, anywhere you find them in the Yahoo! Video product. On the "My Favorites" page you can designate your favorites as private (only seen by you) or public (seen by anyone.)
When you save to your Favorites you can add tags to categorize the content. Think of tags as keywords or labels that you use to group common items.
To view your Favorites page, click the "My Favorites" tab. From there you can click any saved favorite to remove it from your Favorites page or add a tag to it.
To share your Favorites with friends:
Please note: The "Share Your Favorites: Make Public / Private" link on the My Favorites page lets you control the access level for all your saved favorites. When you save or add something to Favorites, and your favorites are set to “Make Private”; only you can see it, even if you share it through email, Yahoo! Messenger, or Media RSS. When you share your Favorites, if you want to be sure they can be seen, use the Make Public / Private link located at the top right of the My Favorites page to set the access level for all your saved favorites.
