Hi,
I've been playing guitar on and off for almost 20 years. When I joined I started with Lisa's Guitar Fundamentals course. Even though it was remedial for me she covers everything in such detail that she tied together concepts I've been missing forever. If any course feels too easy in the beginning, just wait. Every instructor here is a guitar wizard and will get you out of your comfort zone before you know it.
I'd also suggest trying a couple song lessons. They are fantastic here and are incredibly accurate to the recorded songs.
Have fun!
Chris
