This is the translation project home page. Please join us and let us know which language you will be able to help with. You will need to signup with crowdin and then go to the JCB project page and select to join.
We are also working on the option to easily push and pull translation strings via the Crowdin API. This will mean that you would also in the near future be able to with much ease boost the translation of your components via Crowdin, open-source projects are free! At this time you can already use them by exporting the translations strings from JCB and importing it at Crowdin manually, but we hope to improve this integration.
