you can use the url in the message section markup. just go to FAQs and it explains that (thanks to Mike Teets for reminding me) simply put in the markups and between them enter the url that you have the file, i.e.,
<br>http://www.catsailor.com/Art_CNT_May98.html
<br>and that will set up a hot link to the file.
<br>Thanks for your patience,
