I'm very happy to work with Mathemagenesis for a series of Blender videotutorials in my native language (Greek). Mathemagenesis is an e-learning platform with lots of videotutorials covering a huge variety of programs from Word and Photoshop to Joomla, Blender etc. I'm very glad to cooperate with them along with my work here on blendbend. If you're interested take a look over at mathemagenesis.com
Sample chapter video is here.
