FS-UAE now has an unlimited/free open-source account on Crowdin — Translation Management Service. I have a tested the system a bit and it looks really nice. This should help to reduce the effort to support translations, and also make it much easier for several people to collaborate on the same languages.
When the I have set up the project completely, I’ll post instructions for how translators can import the existing translations into Crowdin.
Many thanks to Crowdin for the free open source project support 🙂
