Like every large organisation the Chaos Computer Club doesn't get by some bureaucracy. The office manages all your matters regarding your membership or Datenschleuder subscription.
From the office, to identify you easily, you'll get a small (at the time 5 digit) number assigned. We call this number Chaosnummer (chaos number) and almost doesn't hurt at all. Once you became a member the office will make sure that your name appears on your designated Datenschleuder and the cash desks at the Congresses and Camps knows to give you a discount. If you let the payments slide for too long the office might send you friendly payment reminders as well.
You can get in touch with the office via e-mail at email@example.com, and we recommend -as for any e-mail communication- to encrypt your e-mails to us using PGP (our key). The current key's fingerprint is:
