Root was very easy.
User took a fair bit more time because there were a few rabbit holes. There are also a couple of different paths you can take, particularly from user #2 to user #3. Mr John (with a conversion) is one way but there is a much faster shortcut.
I did Mr J first and then post root, went back and did that faster shortcut. I think it was more fun doing it the long way though.
This was one of my favourite boxes. Easy but still gets you thinking how a file is important until you find the thing that puts those two together.
