Thanks for your input.

I acknowledge that I've underestimated time and efforts but this won't be a classroom for free. The stacker who will lead the classroom on a given day would be forwarded all the sats or a huge portion (in case others are also involved) portion that the lecture post will get.

For time, I think we already have a lot of material on basic to intermediate level topics. It's just that we can align them to the classroom post by pinning or quoting or may be reposting as link.
