over the text where you want it to be linked lay a button (hope you know how to make buttons).. this button set the alpha to zero..so it becomes invisible..this button you can use the get url action and type mailto:name@whateverurl.com
If you create an invisible button with alpha it only increases the file size (ok a little bit).
Best is to fill only the 'hit' stage of the button, this way you save 1 or 2 Kb and it's invisible.
