Here is a set of german translated strings for UBB7 Beta2. The file is bigger than 100kb so you can
download it here.
After download just unzip and load it to your webserver in the designated directories. This archive contains 2 small images. I use them in my language strings for a pointer and the 'top' link. Just upload it too.
After Upload the files go to your control panel and activate the language. Please note: Changing the language per user is not possible in UBB7 anymore. This feature is gone. Sad but true. If you switch you your board to german it appears in German for all users.
If you have suggestions for better translations or found some syntax errors plead post it here, I go and change the archive file step by step.
