Just updated @translator ([email protected]) with a new feature! It can now be used to translate existing statuses.
To translate a status, reply to it* with "@translator [language_code]". @translator should then reply with the translation.
* Probably want to set the visibility on this to "Direct"
* Make sure to use [email protected] as opposed to the @translator on your local instance
* List of language codes and additional instructions here: https://goo.gl/t8h2YS
