That would be great if we can translate Syncthing, to use it in different languages. We could use something like Transifex to submit translations. And then implement those traductions into the web UI
I’m avaiable to make italian translation, if can be useful! 
I think this would be awesome in general. However, I think it won’t be really smooth until we hit a 1.0 or at least a significantly slower release schedule than today. As it is, I release new version once or twice a week, often with new UI or language changes. If we had four more languages in there, that’s potentially four people that need to coordinate and do their stuff before a release can be made, all on a voluntary lack-of-schedule basis. I get the feeling this would either block releases, or I would need to make releases that are only half translated etc.
