What Parts of FastComments are Localized?
All FastComments products that are embeddable in your application or website, are localized.
All emails are fully localized. The locale used to render the emails we send are based on the last locale the user used when they last logged in or commented with the commenting widget.
The admin and user dashboard is not currently localized, however it is on the roadmap.
