Use Weblate for translations

[comradekingu]

I did contribute on Transifex and on Launchpad

I never accepted the updated Transifex terms for EU-GDPR, and the translation has since fallen behind.
Be that as it may, the main issue I am having is with libre software using and strings entering the closed Transifex TM.

Weblate is libre software and a much better tool.
The ability to see multiple languages at once and navigate between strings makes it much easier to use.

#4274 and #3087 are relevant

Edit: I can help with setup, either https://hosted.weblate.org/hosting/ or self-hosting.
https://hosted.weblate.org/projects/super-tux-party/ is already on Hosted Weblate :)

Sorry, atm https://github.com/supertuxkart/stk-website is done on transifex too and as far as I know weblate doesn't support .md file

Using transifex for both stk-code and stk-website allows same group of people doing similar thing
