thanks for the German language pack for the HotPot module for Moodle 2.x
I am not entirely sure how we add language packs to Moodle 2.x modules, except to say that I don't think they go in the module's main folder. I think you are supposed to add them via AMOS, somehow.
Could you contact the official German translators for Moodle and ask them how to proceed:
Actually, I have recently received a Portuguese language pack to (thanks Mariana!), but again I am not sure how we add it.
Please give me a few days to investigate - actually you better give me a week because I am just off to Tokyo for the Japan MoodleMoot - Yay!
