Instructors should be able to keep improving BMF.io courses as time goes on. Stuff changes pretty quickly, especially in business and finance, so courses need to stay fresh. Letting teachers update content, add new examples, or fix things based on what students say keeps the courses useful and interesting. It also shows that BMF.io cares about giving people good info, not just some one-and-done thing. Plus, updating things regularly helps learners get more out of it. It's kinda like updating your favorite playlist—keeps it fun and relevant. So yeah, letting instructors tweak and improve their courses over time is definitely a smart move.
