This 18-minute lesson is free on Nostr. No need to send me a zap to watch it. But if you want lifetime membership of the entire 16-hour Russian course (includes lectures and interactive quizzes to test understanding), then you pay me and @Iryna 8000 sats. You can zap this note (or any note!) 8000 and I will send 4000 to Iryna, as we made the course together. The entire course is hosted on my website. It isn't hosted on Nostr, but it might be one day
