Well, is there a script where I could renew my certificates if I did something wrong? And, belonging to that, maybe an easy howto, if I want to renew my original certificates from the debian howto...if that's possible, to enter other contact-informations.... And second, the suspected-spam contact-question...what do I normally enter here? For now I just used an existing email-adress, but should/can I use an alias like admin for that? Or missunderstand this question wrong, when it's asking for someone like postmaster...
