That's cool Ron. We're doing the same thing! Post a pic of your guitar if you get a chance.
Ya the Justinguitar site is great. I really like how he explains things clearly and takes his time on the lessons. I'm about 2/3 the way through the beginner section, and currently working on switching between D, E and A. My fingers are slowly starting to remember where to go. But they ache!
Edit- Another good site is http://www.chordbook.com/guitarchords.php
What I've been doing is selecting chords to play, then saving them (Button on left side of the guitar).
Then go to "My Chords"and hit the replay button (next to the stop button) It strums all the chords you've saved. Real challenging to try to keep up with the chord changes!
