Where are the Proving Grounds videos? Are they all organized and thumb-nailed or listed on a single page or section of the website? Or are they scattered all around?
Happening by accident upon a couple of them, from their URLs they appear to be in the Blog section. But there is nothing on the Blog homepage that I have been able to find that says “Proving Grounds” or otherwise provides a link to an organized list of the Proving Grounds videos.
