Thank-You for your response. Your response brought up some other questions. I have just purchased the winzip and extractor to create a .exe file of my four courses. Your mention of Stuffit made me think, should I use stuffit to create both Pc and Mac downloadable files or use Winzip for Pc and Stuffit for Mac? Also which version of of Stuffit should I get to create Mac executable files?
Another person mentioned to me that people are more apt to download PDF's instead of exe's files. Have you seen any resistence to downloading exe's verus Pdf"s.
Once again Thank-You in advance for you help and consideration.
