All I can see is your hyperlinks underlined, not all text.

To remove this go to Styles > Edit > General CSS Properties > Body > Special Link Properties

Here you will see 4 text boxes. Just enter the following in to these boxes.

Code
text-decoration: none;
You might want something different in the last one (Hover Link) to make it mor obvious that it's a link. For example:

Code
text-decoration: underline;
