OpenOffice.org 3.0 in 76 Languages
Kazunari Hirano points out that OpenOffice.org 3.0 is officially delivered with support for 69 languages, while 7 more languages are available thanks to the work of community members from linux.cz, bringing the total to 76 languages.
That makes OpenOffice the most multi-lingual office suite available (I count 38 for our competitor), a fitting but not surprising achievement for an open source project with contributors from every continent and users in every country of the world.
