@JoshFossgreen Maybe an intermediate course centered around repackaging your YouTube vids? I stumble across them regularly. Sometimes it’s stuff I can use now (or at least be aware of), sometimes it’s way over my head (and just a mental note for the far future). Even though it’s stuff you’ve already made freely available, repackaging it might be worthwhile. A lot of the strength of your instruction is from its organization, and knowing when to introduce a topic. That existing material would be even better if suitably organized, and workouts included.
But you already have a bunch of ideas, and I’m in regardless
