Translate the content German - is this correctly?
Welcome as a Userbase translator.
Your translation looks fine (but note: I have not checked the actual wording :-)
Don't count on feedback for your translations - we have a lot of pages and translators don't normally patrol them regularly (or at all). We count on translators to know what they are doing. There is a translator team for German (see Translation Workflow); you might try to contact the leader Sordon.
