What about other languages for JTS3? I can fully translate it to russian if you want :)
Currently the JTS3ServerMod itself can't be translated, but this is on the long-term ToDo list. Currently only the Web Interface and manuals can be translated. But also Russian YouTube videos, showing how to install the JTS3ServerMod could be helpful.
Feel free to post them here: https://www.stefan1200.de/forum/index.php?board=9.0
Video renderring is hard for me, but if you drop me lang files for Web Interface and manuals - i will translate it
If you want, you can start with the manuals from the public version.
