With LifterLMS you can offer courses individually or offer access to groups of courses at once through a LifterLMS membership.
Courses can be in multiple memberships.
You can also restrict access to content outside of the course to a membership. For example you could have a bonus resources page, private forum, or specific blog posts restricted to a LifterLMS membership.
With a LifterLMS membership you can even bundle in other offline offers to your offering like a live event, coaching calls, or physical products.
In this example you can get Chris's premium course called Beginner's Guide to Building Successful Online Courses and access to weekly coaching call with Chris by becoming a Gold Member.
