You can activate/deactivate languages you want to use for training the EmailTree application and to reply to emails by going to the Users's menu -> Settings -> Languages. French is set as a default language.

To activate/deactivate languages check/uncheck the box in front of the language and click Save.

Activating/deactivating languages will have an effect also on the languages available in Training History and Blocks that are found on the main menu bar.
