I just read about PayU2Blog they say you get paid 5 dollars or so for 90 words or so. Is this website legit? What blog can you use? I figure it wants its own advertising so I am interested in hearing how this thing works?
I don't know anything about the site, but no, you cannot use your hubs as content somewhere else. If you post something on HubPages, it should only be posted here, and not elsewhere, or you'll get flagged for duplicate content.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
