I took like an audience building class a couple of months back. I used a platform, it was all on a platform called Maven. And the courses over there are structured in all sorts of ways. There's like four week long courses meeting once a week and they're meant to kind of fit for professionals. They were maybe an hour and a half each. So it was engaging because you're doing it live. You're learning with other people, you're swapping notes. We might do projects together. But this day and age, they're all remote.
