To add a link to your web page you would use the same HTML editor that you use to create your web pages in the first place.

The HTML code for a text link is e.g. <A HREF="http://ViralURL.com/Your_Folder_name">The text of your link here</A>

Just replace Your_Folder_name with your actual folder name that you chose during signup.

Personally I use and recommend Macromedia Dreamweaver.  But if you need a free WYSIWYG HTML editor (WYSIWYG = What You See Is What You Get), please visit:  http://www.nvu.com
