I made a Dutch translation of Marketpress. It's not complete (but the most important things are done) and might have some little mistakes. But it's certain a good start for anyone who wants a Dutch Marketpress shop!
I will keep on working on the file, so check this place often. If anybody else feels the urgency to work on int you are more then welcome.
I'm thinking of letting someone building a Marketpress IDeal plugin? Anyone interested in sharing the costs?
