Success message

When you register on bekijkdithuiseens.nl, the register form is shown in a fancybox. When you submit the form, the fancybox flips and you'll see the message above (it's in Dutcht; it says: Perfect, let's get started...we've send you a e-mail with the activation link. Click on it to start right away...- well, something like that..)
Any thoughts?
