Great to hear! It has been almost seven for me. I wish I had kept a diary of the chords that I learned. I know it was about 2 years before I could do a good Bb chord. (I could make a Bb if I was just sitting around but hitting it during a song, without stopping, took about 2 years.)
Congrats and Happy Anniversary kaizersoza! I can totally relate to it changing your life, all for the better. It's been 4 1/2 years for me and a day hasn't gone by since then without something uke related.
