Alan Liefting on "[Theme: Twenty Ten] Too much white space above footer"

I have the twenty ten theme on two sites: http://www.nzvintageclub.co.nz/ and http://www.ecotechservices.co.nz. There is too much white space above the footer and we cannot find were it comes from. It is nothing to do with the social media plugin that appears just above the footer line (AFAIK)
