If you're teaching on BMF.io, the trick is to keep your course easy to use but still fun and fresh. Make sure everything's simple to find and not confusing—no one likes getting lost clicking around. But don't be afraid to throw in cool stuff like videos, quizzes, or interactive bits to keep things interesting. It's all about mixing old-school basics with some new tech without making it too complicated. Also, check how your course looks on phones and laptops so it works everywhere.
