Wow! He sure packed a lot of great info in there... hope to see more from you in the future Dale, but I'm sure those lessons will keep me busy for a while... Nice job!
For all you acoustic guys who haven't checked it out, here's the link:

This is not a beginner lesson (though that doesn't mean you still can't check it out)... you'll want to have a solid understanding of open chords and maybe some fingerpicking before you try to tackle these lessons. Also, be warned that when he goes through the chord variations, he's just showing you the chords... so it may seem a bit over-whelming and not very musical (because he's just showing you the finger placement for each variation). In the last couple of lessons is where he puts it all together... love the encouragement to experiment with variations & picking patterns... cool stuff!
