2007 Office Compatibility
[Excerpt from email]
"...
I recently installed 2007 Office and am having trouble exchanging documents with people in the office on Office 2003. How can I fix this?"
Your peers in the office can download the Office compatibility pack (FREE) or you can save your documents in the Office 2003 format by clicking File>Save As
(I am surprised that even after 1.5 years in market, folks are having trouble with the new file formats, hence the post.)
