The Sensei Course Participants extension shows visitors how many people are currently taking a course.
Once installed and activated, you will see a message on course archive pages and single course pages displaying the current number of learners taking the course:
There is also a Sensei Course Participants widget you can add to any widget area, via Appearance > Widgets.
The widget will display on course, lesson and quiz pages, and will show the display names of all learners taking the current course.
If your site has public learner profiles enabled, the names will also link to the learner profiles.
The widget will also display the learners’ gravatar image if they have one.
All of the settings for this extension are within the widget itself. You can set a custom widget title, and change the image size and the order of the learners.
You can also set a limit on the number of learners displayed initially, and then the rest of the learners can be shown with a ‘view all’ link at the bottom of the widget.
Finally you can choose to display the learners as a list (with names) or as a grid of images (without names).
