I think for all parties, if we had the ability to send a "two day backstage pass" (you can use that), where we can send a friend a link and they could try the sight for free but couldn't submit videos. I have a few friends that I keep trying to sell them on but they just are not totally sold and I think it's because the beauty of this site is the personalized VE's are. The interaction between student and teacher is what really makes this magical and it's really hard to describe. The search feature could be a little better, more precise and sometimes it finds no VE hits on simple searches like street. Otherwise I am one of your biggest fans.
Guitars have been played since the Renaissance era, after descending from the ancient Greek instrument, the kithara. Or, at least, that's how the theory goes: the only real proof for this is the similarities between the Greek word and the Spanish word, quitarra. Early guitars often had four strings, evolving into the six-string version we know today in the late 1600s. Anton Stradivari, the famous violin-maker, also had a hand in making guitars. There's now only one Stradivarius guitar left in existence.
