Looking For Free Online Educational Material

Q: I just bought a new nice guitar, and now I want to learn about the position of the hands and other technical basic lessons. I previously studied classical music, piano, composition and conducting, and I've already started playing - what a rich and extensive instrument! But I don't want to do something wrong at the very beginning, like positioning my hands wrongly or someting like that. I'm looking for free online resources for technical practice and the like, through which one gradually attains the skill

A: I find www.guitarnoise.com to be a very useful on line free resource. Also check out www.wholenote.com
