Not sure if I can quote the faq for Hubpages here, but the help and faq for this site explains Hub Scores. Just click on "Help" in the upper right-hand corner. And you might also see what I see now on the right side of the page. There is a link to "Introduction to Hub Score/Hubber Score". Hope this helps.
