There is a Bitcoin Meetup coming to my area in a few weeks. I would like to see our time together be productive beyond the socialization. Does anyone have ideas for a topic(s) that could/should be covered in an hour or less of a 90-120 minute meeting? I'm thinking it would be useful to teach/ learn how to use the lightning network for micropayments. Are any of my inland Northwest compatriots adept at this use of the technology - willing to bring a lesson plan of sorts to our meeting in October?
