In general I love the GuitarTricks site and have found it extremely helpful. I do experience trouble navigating the site, in the sense that I accidentally discover a lot of great content. In another forum message, Christopher Schlegel pointed out he had a lesson on posture. I never saw this when I went through the Guitar Fundamentals, but sure wish I had. I would like to suggest adding some additional browsing capabilities. As an example you have buttons for "New Course From Anders", "Old Course From Lisa", which is helfpul. Maybe expand that to point out additional beginner topics. Even another button with "More tips from Christopher" would be great. 

More generically, having a breadcrumb trail on every course would be nice. For example, on the link Christopher pointed out,  I can easily see there are five chapters associated with this tutorial. What I can't tell is if these five chapters are just stand-alone content, or if they are part of a larger course or lesson.

GuitarTricks has obviously put a lot of thought, care, and quality (production and andragogy) into the lessons on this site. It's a shame that some of it is so hard to discover. 

With love and gratitude.
