If you need me, I would be glad to contribute to the Dutch localization.
I am a advertising copywriter by training and have some experience in software localization. I wrote the guidelines for the Dutch translation of Magento (_the_ open source e-commerce software) and coordinated the actual translating. About six people contributed, me acting as the "editor in chief". Of course, I did a lot of translating, too.
Hope I can help.
