Dennis, I'm interested in following your progress on this. Something that would help me would be to make your links more useful by displaying a meaningful name rather than the document URL. I've changed one as an illustration.
To do this in the WIZWIG editor, type the the text for what you want the user to see and then select it. Next click on the "chain link" icon (top row of the editor tool bar). You don't need to fill in all the options; the important one is the link URL.
