The [office](mailto:office@ccc.de "Chaos Computer Club 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 4 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](http://events.ccc.de/congress/ "Chaos Communication Congress") and [Camps](http://events.ccc.de/camp/ "Chaos Communication Camp") 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 , and we recommend -as for any e-mail communication- to encrypt your e-mails to us using [PGP](http://en.wikipedia.org/wiki/Pretty_Good_Privacy "PGP") ([our key](/system/uploads/145/original/Office-2014.asc)).
