Thanks for the feedback! Yes I got a professional voice actor to narrate it as my voice is way too dull and I didn't want to send people to sleep ;)

I will definitely plan to auto-mark videos as watched and also produce a completion certificate - these are great ideas, thank you.

I also plan to make the video page layout more like YouTube, with the video window taking up 2/3 width of the page and the list of videos taking up the other 1/3 width down the right hand side. Unfortunately I don't yet have the tech skills to do that, but working on it :)
