I offered to act as Dutch Translation Team Leader in the Devs section.
Before translating anything I want to urge you to actualise the dutch language file and add all lines that are not there at present version.
Then make a section in the language board where you place all changes since you've updated the file ( you only have to update the file with the missing variables in English, we or I will translate the necesary stuff and post it back online here)
Anyone who wants to be part of the Dutch translation team will have to signup and DO THE TIME, otherwise nothing will happen and you end up with the same outdated files you now have.
If you like this, contact me by e-mail not by PM.
