Glad to hear you are enjoying it. It's so easy to quit playing guitar when you are struggling on your own in the beginning. I was like that the first couple of years where I would not know what to work on next and ended up not playing for weeks or months at a time.
I like the structure on the lessons here and I also like that there are a lot of song lessons that interest me.

Another cool thing I got from here - I've stolen some cool riffs from some lessons from Neil Walter and Anders Mouridsen and then added/changed them a little and wrote some songs that my brother-in-law (bass) and son (drums) can jam to!
