These are videos of (fantasy / scifi) writing classes taught by author Brandon Sanderson. http://www.youtube.com/user/WriteAboutDragons
I can't stress enough how much information this author has.
I apologize that it isn't in the most clear order but each video is labeled with a couple-word description and is numbered.
I've been watching these for the past two or three days and have taken notes.
I hope you enjoy them as much as I have!
