Thanks for the encouragement :) I am indeed still plugging away, even if the process is not as easy or as fast as I would like. And it is fun nonetheless -- I am in love with the instrument: its size, the physical immediacy of the sound it produces, the charming ease with which you can play in C. It would be nice to think that I'll end up actually being good some day, though. We'll see.

Have you gone back to the piano as you learn guitar? It's arguably the ideal instrument for theory...
