I would like to request a full review of LearnDash. A tutorial would be nice as well.
From your Course Website Tutorial, I think you chose LifterLMS because it has an excellent and full-featured FREE version.
However, if you want to make money you have to pay $99 for Paypal and/or $99 for Stripe ($198 total) per year. And its add-ons rapidly become very very expensive. You get heavily tempted to purchase their full suite for $999 a year by the high pricing of add-ons.
For $159 you can get LearnDash with Paypal and Stripe and Woo Commerce for FREE plus you have the option of using Membership plugins like MemberPress, Restrict Content Pro and PaidMembershipsPro if you want these to handle payments.
Is it easy to make the course look attractive in LifterLMS vs LearnDash? That is an important point since the courses look generic in both without more design.
