Hola Shannon

You can't add vocabulary lists to your notebook, but you can add them to "your own notes". You need to create a notebook first. For example, in this case, you could create a notebook with some lessons that are about the masculine gender. If you go to your dashboard and do a general search (at the top) by typing the word "masculine" kwizbot will find you lessons to do with the masculine gender. You can add some of those to your notebook. Then, once you are inside the notebook, to the right you'll see "My Own Notes"; here you can copy paste the URL of that studylist you want to save. The studylist won't show as a hyperlink like the lessons do, but you can access the list whenever you want. 

I hope this is clear and helps. If you still struggle with this please let us know, so we can take it to the Help Desk and give more detail information about how to do this. 

Saludos cordiales
