Hey John,
Sorry for not replying! I somehow missed the thread! Thank you for bumping it
The translations for the emails are also part of the normal tranlsation files.
in adminitrator/language/your-languae/your-language.com_comment.ini or
language/your-languae/your-language.com_comment.ini
Also - we use transifex for translations and you can find some of the already existing translations:
opentranslators.transifex.net/projects/p/compojoom-comment/
You can perhaps find there the translation you need?
Kind regards,
Daniel
