Keep up the good work. You have set a standard after the first post.
I've never heard of a belt-system MMA class. Which is actually a good idea, now that more and more people are joining the beloved sport. We have a Beginner, Intermediate, and Expert class, however its very subjective and some people will get promoted to the next class, and won't fare well so its a tough decision. However, belt system would help out with set protocol/standards for such levels. Best of luck to you.
