I've just submitted a patch for the Portuguese translation.
If you are a Django user and know Portuguese, please take a look to the translation strings and submit any fix before the final 1.0 release.
Meanwhile, you can download the unofficial version in the downloads section.
Update: The patch is already in SVN.
Are you a translator by profession? Then you must check out – http://www.translationartwork.com , maybe it could be of some help to you.
