    Isn’t this an old video/series?

      Hello David,
      We are going through and re-organising some of the videos to make them more easy to find.

      Remember, some of us haven’t seen the old material before… Unless there’s something that needs to be marked as “oops, I show a better solution [here]”, it’s still perfectly useful!
