[Small-cl-src-discuss] licenses?

I've been reading the code snippets with great interest and appreciation. But I've been a little nervous about using any of them, for fear of raging attack lawyers. :-> More seriously, I don't want to abuse anyone's confidence by adopting code they were just sharing for pedagogical purposes. So, I was wondering, would people mind letting us know what sort of licenses they are putting on these code snippets? Or is there some standard license implied by posting to small-cl-src? Thanks, R
