Just can't find the file...

On every page in Site Frame 3.2.2 there is a line that gives the date and "by". I want to get rid of "by" but can't find the file to do so. I am very impressed with Site Frames light weight fast loading pages. If I am unclear you can see what I mean here http://www.betterbusinesscards.biz/w2/document.php?id=4. Any help is greatly appreciated.
