The bigger issue for me for is that I often jump ahead to just peak at, or print notation, for future lessons.  As a result, it says I completed it.  There is no way to unmark it.  The admin will say there is a way, but it does not work.  I've documented that it does not work and sent that to them.  Then silence.  

Lately I've been looking at other learning sites (guitar, piano and other learning sites in general) and some of them are so far ahead of GT.  The interfaces on this GT site are embarrassingly antiquated.   That and the loss of songs is making me reflect on my future here.  Right now, the only thing keeping me here is my loyalty to Anders, Chris and Mike.  They are fabulous teachers and have taught me so much.
