Sorry but in five days no simple answer to a simple question from the Photopost Team?
It seems that there's no interest in a german language file even if some other users would need it. I only need an answer where to upload the XML to make it available to other users and if it is possible to share it on the site vbhacks-germany.com.
Please see this thread too: http://www.photopost.com/forum/showthread.php?t=118120
Brian has allowed to distrubute the translation on vbhacks-germany.com but now it's your software so I ask you for permission.
