Dutch translations wrong

Hi, i have a question.

How did you translate the englisch text to dutch? Cause there are some places where it looks like you just used
some kinda wrong translation machine.

Here's an example, an automated email to someone who was added to a usergroup:

Jullie waren voegden aan de Writers Clan groepering op "Xamuusga Clan Forum" - http://xamuusga.forummotion.com toe

Deze handeling was geoefend door de moderator van de groepering of de beheerder van de stek, contacteren hen voor overvloedigere informatie.

Words in blue are incorrect translations,
Bold words use the wrong grammar.

Maybe you don't read dutch, but there are more places where the dutch language is incorrect.
Can this be fixed, if not, where can i set the language of these mails and stuff to english?

Hi,
if you wish we will to help for the translation, we can give you access to the translation tools

That's sounds ok to me
