I got this edu link from a list : http://faculty.virginia.edu/MyTube/fall2009_adspotlights/2009/11/04/negative-advertising-in-the-08-presidential-contest/ . I want to put my backlink here. There is np place to put backlinks but there are many trackbacks. I want to know how to do that? How to create those backtracks? I have seen it at many places but don't know how to do.
