Hi everyone. @Wimpy has successfully integrated Welcome into Transifex, which will make translating much easier – it is web based and offers more features to ensure quality translations, like reviewing. 
For translations that have started with Git and Poedit:
In order for the translations to be populated, please commit your partial translations so far and proceed to creating a pull request. Help if needed can be found in the previous guide.
I hope this isn’t too inconvenient switching systems. Once @Wimpy accepts your pull requests, they’ll be pushed and ready to translate on Transifex. Hang tight! 
New home for translations.
A new guide is available:
