How to configure phplist for multi-language use? [Solved]

Is phplist not ready as a multi-language newsletter system or do I miss something?

Under “Settings” » “Transactional settings” I can only enter subscriber communication in one single language.

Sure, campaign templates allows to enter language-specific “transaction messages”.

However, it misses configuration of many strings that are only configurable under “transactional settings” (e.g. “Subject of the message subscribers receive when they have changed their details”)

Any help would be very much appreciated.

Please disregard.

It seems that the language selector in the subscribe page settings cover different languages for the transaction emails.
