Thanks, Lori. I appreciate your kind words. There's still a lot to do, of course, and I add to it or tweak it almost daily. Working on a ukulele anatomy page right now.
On another note, the Uke Leash just arrived in the mail an hour ago. I've been busy doing some housework, but I managed to slip it onto my Kala and take it for a spin around the dining room. Works like a charm! I haven't tried all the components, nor have I tried it on other ukes, but what I've seen works beautifully. Will spend more time with it on other ukes this weekend, and post my updated notes online.
Just a thought: I got the 'medium' size, I believe. I hadn't though much about how I hold the uke, but with a strap, I hold it much lower than without one. So I'd suggest you might consier adding another 6 or 8 inches of strap to the length so it doesn't cramp the player's style. Or sell one size (large), but add a second buckle to tuck the excess into.
