I have something else that could help you Anno; After
our discussion at UBBCentral I now have a script that merges the newest english language files with as much information as possible from the old and outdated translations. The result is written to new and complete language files with partly english and partly translated Wordlets, ready for your translation job.
I have no idea yet where to provide this script and its results (maybe best here at Threadsdev), and it needs a bit more fine tuning, but the first results look promising! If I had the 6.4 files I should be able to provide you with up-to-date merged files.
Could this help you?
Tjerk.
