My Drupal 8 Beginner Tutorials course on YouTube just hit 3,000,000 views! What a privilege to share Drupal with so many people!
I travel all over the United States teaching Drupal. I suppose I should have kept better track - but the number of students is around 800-900 over the past 9 years. I love teaching people and seeing the "light come on over their head".
Here's the link to the course: https://www.youtube.com/playlist?list=PLtaXuX0nEZk9MKY_ClWcPkGtOEGyLTyCO
