I checked the links ....they seem fine, but nevermind them.
As for your question, I don't exactly understand what you're looking for in my answer, and what "people animations" are you refering to. You've got to be a bit more specific about what you want. Don't say just people animations, describe an entire sequence (not to long for now), and I will gladly go over every aspect of it with you.
As for your question, I suppose I'll just build a character and a skeleton to match. Buit if you're refering to key framed animation vs. something else (i.e. motion capture), then I'm afraid I don't have the recourses for anything besides keyframing.
