New format trial

In order to get more tutorials onto the site I am going to just add links on the appropriate category pages. It means there will not be new posts with embedded videos as previously. It also means I am relying on the descriptions and titles of tutorials as posted by their creators, and I will not have vetted them to see if they are any good. Please let me know if I make any mistakes in the comments. I will add the tutorial titles to the weekly round up page but there will be no link to a page.
