Recently, at the National Association of Government Webmasters conference, a few people tried to download my presentations, but could not open them.  As you might guess, I use Office 2007.  All of my recent presentations have been saved in the new file format.  If you are a PC/Office user, then you can download and install the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats.  This will update your Office applications to Open/Save in the new Office 2007 file formats.  If you are a Mac user, then have a look at the Microsoft Office Open XML File Format Converter.  If you are using OpenOffice, then have a look at the OpenOffice OpenXML Translator.  If you are in a position where you cannot install software on your work computer, then please contact me directly and I will send you a copy in the old format.  Why not just upload both formats to my SkyDrive?  I'm a bit of a "slide tweaker."  I rarely go two presentations without changing something.  Keeping my blog, Windows Live Space, and SkyDrive up to date is quite time consuming as it is.  Having to maintain all of my presentations twice would be less than ideal.
