How do you get extras for pivot animation

Well how i did it is i just searched google stuff like.....pivot extras,pivot weapons,pivot characters............STUFF LIKE THAT... ^^ that is one way... But there is a thing called droidz.org which is a whole site based on pivot stickfigures and it even has a forum! another place where you can even request .stk files is darkdemon.org which is a forum also.
