There is a Kontera hack circling around the blogosphere, a hack where you can change your Kontera text link from double underline to single underline by adding this following into the Kontera code:

• var dc_single_line = ‘yes’;

This made the Kontera text ad links blends perfectly into your content, like a normal content hyperlink. However Kontera officials are not really encouraging this as it would confuse your readers. So by putting single underline into practice, you could have your account suspended. Just a note for those who are eager to try it out.
