It is easy to use and you can have unlimited members.

Marble allows me to build courses quickly and easily. I love the easy to use interface and the ability to create my own themes for the courses.

I absolutely adore the LMS interface. I've used FreshLMS, LearnDash and a few others, they have their own merits but if you want your course to make an impact, you need to extract the junk on the page and be able to seamlessly deliver content. Marble have done an absolutely fantastic job with this. Also they load time is super quick. No one is willing to wait around these days, so it's wonderful in this regard.
