I’ve started to implement the use of Transifex for keeping kiwitrees translations up to date.
This means no more need to download .po files, and no need to install poEditor or any other special software.
The only time you might need those would be if you want to update your own site with a new .mo file (the actual binary file needed to make translations happen). You can download the latest po file from Transifex, then just use poEditor (or any other) to convert it to an mo file.
But otherwise, just update on Transifex whenever you see new language strings listed, and I will create new .mo files at each update of kiwitrees.
I will try to write some brief instructions for using Transifex when I have some time, but they do have pretty extensive documentation on their site anyway. Just visit the URL above, sign up with Transifex , and get translating 🙂
(As yet there are only a handful of language file there, but I will get the rest uploaded soon. Remind me if yours is missing.)
