Release 1 of the OpenXML Translator for Microsoft Word is now available through Sourceforge.
This tool allows MS Word users to open files saved in OpenOffice Write format (.ODF), make modifications and save the files.
Microsoft is due to release this through its website shortly, and apparently there will be Impress and Calc converters, too.
For people who are considering using OpenOffice, or use both OO and MS Office, this is definitely good news.
The tool will work in both Word 2003 and Word 2007.
