How do I bookmark scripts, mark them as read, or save them to my favorites?

You can only do this if you are registered and logged in. Next to all other member's scripts you will find these icons . Clicking on the bookmark icon will add a script to your My Bookmarks page which can be found in the top menu. You can also mark a script as read or a favorite for your own records by clicking on the eye or the heart. This is all private and does not affect listings in any way. Not only should this make managing your own reading lists easier, the long term intention is to use the data to create recommendations for all users.
