Do I need to cite my sources on HubPages?

Alright, here is my difficulty, I have been trying to write some articles on hubpages, they say they want original work, and I'm trying to figure out if they mean original writing or original research, and if it is original writing, do I need to, and how do I, cite my sources, (I've spent long periods of time searching, and I have failed to find any Hub that has its sources cited).
