Underline link from dynamic text

I have a text box that will be updated by my client. I want them to be able to include links in their text, but I really don’t want to require my “not-so-computer-savy” client to have to remember to type this out everytime they need to add a link

<font color="#ff0000"><a href="http://cnn.com"><u>CNN</u></a></font>

is there a way to simplifying this, and still have flashMX recognize it?
