As not everyone talks or understands English, localization support for VarAC client would be a great addition with the VarAC community supporting the translation process.
For example in Finland there is a good portion of hams who don't speak or understand English well enough to be comfortable with it, and thus mostly use modes like FT8 where they do not need to actually communicate with the other QSO party.
Localization so translating VarAC client to other languages would overcome this barrier and enable more hams to join VarAC. Of course then the QSO's are in any given language but it would boost the popularity of VarAC anyhow and make us make more domestic QSOs!
