Lots of us on here! I'm in Boston.
What are you looking for?
As to your other question- I have no idea. I usually refer to myself as a "builder" (or guitar builder/maker) because "luthier" sounds a little fancy to anyone who doesn't already know the word. But people who do know it love to say it
I've heard Al Carruth explain what it used to mean but can't remember the exact definition.
