I've been correcting and updating the Dutch translation. We are working on MM 2.1.5 from Debian. I thought it might be usefull to send the files to this list too. They can be downloaded on http://pub.telenet.be/~luc/mailman/
Also sent to Debian as bug 306748 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=306748
Maybe parts of this translation can be used for the new release?
