Piotr and I have just setup our Tx instance to serve translations for the upstream Transifex project.
Development release: https://translate.fedoraproject.org/tx/projects/transifex/mainline/
Stable (0.6.x) release: https://translate.fedoraproject.org/tx/projects/transifex/0-6-x/
The strings needing translations are around 400, most of them being a few words long. The English file is available for translation from the languages table itself.
Feel free to send your translations to mainline; once in a while we'll msgmerge them back in 0.6.x.
