I created a public project page for freerouting on Crowdin.

I invite everyone to join who can spare a few hours to make and proofread our translations.

Currently we have English, German and Simplified Chinese support, and I'm looking for people who can help with the following additional languages:

• Hindi
• Spanish
• French
• Arabic
• Bengali
• Russian
• Portuguese
• Japanese
• Korean

Every forthcoming major version of freerouting will have updated translations for the languages that hit the 95% completion level.
