How do I do this?
 

I want to make a Dutch review for a game. How do I do this?
Also, how can I find games that haven't been translated to Dutch before?

1. Yoyu need to talk to the person in charge of the Dutch translation project. I think that's Reup's area, but might be wrong on that account.
2. I presume you mean reviews rather than games. It's easier to find the ones that have been translated already, but Reup (or whoever's in charge of the Dutch translation now) should have a list around.
