BlackJack_Jonny has created a great collection of HD Video Tutorials accompanied by narration. It's an amazing quick stop for beginners who have at least got past a couple of the basic text tutorials first. They will also prove to be a good re-cap for anyone coming back to Radiant or just needing some extra tips.
