Luc: Just on last couple of days. Really good stuff mate. My suggestion: Don't worry about upvotes. You'll attract a lot of people who'll be highly critical and make ignorant comments. The bottom line is that many people are fearful or greedy and want a quick fix and don't want to stretch their cognition. I sense a genuine heart for the people/community. Don't worry about not feeling the love, just embrace that you can present high quality instructional material for what is quite a complex blockchain world. All the best, Roger
