The default language for our account is English. However, we also work in Quebec, and I would like to be able to create campaigns of all kinds 100% in French, including the interface on the supporter side (buttons/labels on the form).

Here's an example: https://www.zeffy.com/en-CA/donation-form/des-bijoux-pour-le-24h-tremblant. I tried to replace the “en” in the link with “fr”, but that doesn't work, the interface always goes back to the default language which is English. Thanks
