Hello I consider myself a beginner to intermediate player looking to get better.  Some of the introductory lessons don't appeal to me since I am past that.  Where and how would the best path for me to take.  I like classic rock. Tend to play more rhythm style and looking to expand and get away from just strumming songs.  Been playing on and off for 40 years and definitely have more time on my hand. 

Thanks for any advice on how to best use the tool.
