You can click on the instructors tab then click on Lisa McCormick and it will take you to her bio page, scroll down and it will have a list of tabs and one of them will be lessons that she gives. She gives a lot of lessons on strumming so you don't have to take one of the 3 courses you can go to individual instructors or one of the many Genre courses under the lessons tab.
I hope this answers your question.
