Tony's Acoustic Challenge is great for me since I've been away from the guitar for decades. I was hesitant to sign up because I didn't want to start and then put it back away, but I've been consistent now for several weeks and I am enjoying playing again. In addition, I am learning things I never knew before and that is helping me overcome my fears of doing anything beyond rhythm guitar. I'm not there yet, but I want to consider myself a lead guitarist someday and for the first time, I have confidence that I will get there. I would recommend Tony's Acoustic Challenge for everyone from beginners to advance players because there is always more to learn.
