Nikon is offering a bunch of their courses for free for the month of April. Good to practice your photography skills at home.
Each class is taught by a professional photographer and provides in-depth lessons to help you get better at taking photos. Some courses cover Nikon-specific products, but many of them teach you the fundamentals of photography, such as a course that teaches you how to photograph your children or pets or the basics of making a music video. So even if you don’t own a Nikon camera, many of these classes might still be worth a watch."
I created an account ( https://secure.nikonsso.com/create-nikon-account ) and went to the courses page, and it looks like only the first video is free and all the others are full price.
Probably a mistake by Nikon, but given that it's now a few weeks into April they might never actually fix it.
