Subscription of the Speläoclub Berlin newsletter (SCBNL)

Note: The SCB stores solely name and email addresses of subscribers for being able to send the newsletter to them. After unsubscription, the corresponding name and address is deleted immediately. No names and addresses will ever be given or sold to anybody and we do not use them for marketing. The point of telling us your club simply feeds our curiosity — we love to see which parts of the world our newsletter is going to (not stored).
