I'm struggling with the registration part of the ZP script, I read the tutorials and instructions but I'm not a PHP prof.
I'm not sure if this is important: the language is set to Dutch.

After a user submits the registration, he should be automatically redirected to a confirmation page. If you are not seeing that confirmation page, what exactly are you experiencing?
As far as I know, the only way to customize the registration e-mail is to edit the register_user plugin. The message can be found on line 198 in the file. If you do not feel comfortable editing this yourself, feel free to open a ticket on the bugtracker as this seems to me to be a viable request.
The registration form should be redirecting back to itself to handle the form's POST. Are the registrations going through? If so, you may need to clear your cookies. The registration script should only redirect to the index once registration is complete (the user is verified) or if you are already logged in.
