Can you help validate these translations?

The calculators found here are the result of 35 plus years of feedback from the users who have taken their time to comment and offer suggestions. To those users, thank you! For new users, you benefit from full-featured calculators that have date accurate results.
You don't need to settle for "estimates" like other websites promise you.
Are you a blogger? Are you a successful personal financial blogger who blogs in a language other than English? If so, perhaps we can work together? I can create computer-translated versions of all these calculators. If you proofread, edit, and sign off on your changes, you can have, for free, a copy of each calculator for your website. Naturally, you will get links from this site, credit for the translations, and you will keep 100% of the advertising revenue the calculators generate for you on your site.
