As long as someone has the ability and will be responsible for verifying the quality (i.e. not Google Translate, etc.)... and provided they get implemented on the website, I will add the following bounties:
300 XLB for Spanish
300 XLB for German
300 XLB for French
100 XLB for Russian
This is from Daredev, post #4158.
Add those to the bounties too if you haven't already.
