I have recently finished a 2 year personal project in Cambodia that culminated in my making a charity fundraising ebook/guidebook to Cambodia available for free download over the internet. I published my ebook 4 weeks ago, and am now beginning to recieve some feedback that it is not Mac compatible (it's an .exe file). As a relative newcomer to computing, and never having used a Mac (apologies), I had no idea that .exe files were exclusive of other operating systems. I'd like to ask the board; is there anything I can do to make my ebook Mac compatible so everyone can view it? This is a not-for-pofit project that makes only a small amount of money. If anyone would like to take a charitable look at the ebook and possibly advise as to what may need to be done, here is a download link http://cambodiamaps.blogspot.com/2008/05/download-update-release-v20.html Many thanks for your time.
