Sensei Course ParticipantsDeveloped by Automattic
People are more likely to sign up for a course if they can see that it’s already popular, right?
Sensei Course Participants shows your site visitors how many people are currently taking each course.
There’s also an optional widget, which you can add to your sidebar, to display a list of all the learners taking the course. If you have public profiles enabled it will also link to each learner’s profile.
