A lot of those guys in the 1st generation marked as certified weren't certified by Bruce Lee though, i think that's a little misleading.
I think it would be really difficult to make something like this utterly comprehensive. I know it's a work in progress, so it's probably folly to point out that so-and-so isn't included. (And it's part egotism on my part, as well, but none of the instructors in my area are featured under Guro Dan.) Stuart
Am with DaeHan and Fire- think it misses the point, ultimately. It's complicated though, because while I think it puts us in the same place we always are (what is/ain't "JKD"), I think it's important to have some quick way of knowing if someone has relevant material.
