The problem with MS Office 2007 documents is that they have to be saved in a version other than 2007 if you are planning on sending them to anyone who is not using the 2007 version. Now those of us who use OpenOffice (the open source software) have a translator available that should allow us to read Office 2007 documents. The OpenXML Translator allows you to
"Expand OpenOffice.org's document opening, saving, and conversion powers to Office 2007 documents with the Open XML Translator, a free plug-in intended for Ubuntu systems."
I'll have to try it at home tonight!
