You can check, edit or delete your registration by using this
In order to check, change or edit your registration, you need to use your personal user code, which you received in the confirmation e-mail when you made your registration.
When you have finished your changes or deleted your registration, you will also receive a confirmation e-mail on the e-mail address you used for registratration. This e-mail will at the same time be our confirmation that your changes are registered.
In case you DO NOT receive a confirmation e-mail, we once again ask you to check the SPAM-filter provided by your e-mail provider. If you are unable to find your confirmation e-mail , we urge you to send us an new e-mail to the address “firstname.lastname@example.org”, allowing us to check if your changes are registered correctly.
