YIKES! I had no idea there was a video for this! I guess I should have taken more advantage of the search function on this site. I've been looking at nothing but the "Absolute Beginner's Guide to Guitar" (Level 1 and the beginning of Level 2) section. I think your lesson should definitely be included in that guide!
