If you do, take notes, and let me know every part they have a problem with. Usually there's some "magic word" or missing bit they didn't know, or that exercise is just total crap.
My brother agreed to try it once school is out in a couple weeks. I think he's a pretty good candidate: computer savvy and uses a mac, is interested in what I do but has never tried to learn it before. I'll definitely take notes and pass them along.
