Rule n° 80 - Custom error messages are expressed in the language of the form.

When designing forms, professionals focus on visual appearance and ease of use. Error management often comes later in the design process. Sometimes it is the developers or content management systems that take care of error management, and this is one of the cases where error messages are found in another language than the original form. This can be annoying to users and can damage the image of your service.
