As we are getting closer to release of XOOPS 2.5.12, we would like to make sure that the Core translations are done for it.
I uploaded to GitHub translation done by AI for the following languages, but we need native speakers to review it and correct any mistakes!

Arabic
Brazilian Portuguese
Chinese (Traditional)
German
Greek
Italian
Japanese
Persian
Polish
Russian
Spanish

We also need help with other languages - take a look here: https://github.com/XOOPSlanguages

You can do the translations by downloading the files from GitHub and then submitting your changes, or you can use Transifex, as it was described by Goffy.
