From 27C3 public wiki

Jump to: navigation, search


Like each chaotic event the 27C3 will not be possible without the help of many volunteers. You can be one of them. Lots of volunteer work needs to be done before, during and after the event. Volunteering is actually a lot of fun. You will work with other people who share your interests, learn a whole lot in the process and really take part in the event.

Even though being a volunteer is not financially rewarded (does that mean that one has to pay the full entrance fee even if helping as a volunteer? YES! You do not even get a rebate.), we need volunteers to make the congress a success. As a volunteer, you will be doing important stuff, meet many interesting people and generally have a great time. Furthermore, we will provide a volunteers-only area with a small Hackcenter and some kind of never-ending breakfast. And of course you'll get a free volunteers conference shirt.


Becoming a Volunteer

If you're interested in helping out you can

  • register at
  • just go to the angel area and just say you want to help. There will be people who show you how.
  • have a look at the pages of the volunteer teams and see if you want to help in one of them and if they need more help. Just contact the coordinator to find out how you can work best in that team.

Types of Volunteers


Conference angels make sure that all events start and end on time. They also ensure that the rooms don't become too crowded when more people want to listen to a talk than places are available.


We need heralds with strong English skills who feel comfortable speaking in front of the crowd at the beginning of each event. Heralds are primarily responsible for each lecture hall from the beginning to the end of a talk. Heralds insure that the speakers are on time, ready to go and properly introduced to the crowd. During the talk, they fix any problems that may arise including coordinating Conference Angels for light crowd control if necessary. Finally, they make sure the speaker wraps up before the session is over to keep the congress moving along. There is also a more detailed Heralds page available.


All events will be archived and streamed. We need people who ensure our cameras (video angels) and microphones (audio angels) are up and running. In addition the angels help handing out microphones in the lecture rooms for questions to the panel.


This is where tickets are sold, badges are fixed/checked and exits are secured. The entrance team includes cash desk angels and entrance angels (former guardian and crimp angels). For more information check out the entrance page. We will need a considerable number of reliable volunteers here.

Guardian Angel

see Entrance


Netangels help the NOC to build the network and to provide support and service to the participants. Basic knowledge of computer networks should be available.


The angels of the CERT (Chaos Emergency Response Team) are the first responders and provide first aid in case of a medical emergency. We are looking after the fire protection in this building also.


Chaos angels and the crew are self-catered. So we need some angels that take care of that. For in fo ask around in the Engelraum. There are night and dat shifts. okkie


With your help, we try to operate the Cloakroom 24/7 during the congress. If you're interested in helping out at the cloakroom, just sign up for a shift in the shift system and arrive in time, so everything can be explained to you.

If there are any questions or problems regarding the cloakroom, feel free to contact Knuff!

Shift System

The Angel System will be used to centrally coordinate shifts and Chaos Angels. If you want to register as an angel, you need to create an account for yourself. You can find the Shift System at

To find available shifts, click "available shifts" on the left hand side, then select the area in which you would like to help out, and then use the date links above the shift table to jump to the individual days. Note the "available shifts" page also contains a "show everything at once" link which shows all areas for a given day. Under "my shifts" you can also cancel your shifts up to 3h before they start.

Please choose your shift there and be around 10 minutes before there, especially for audio and video angels.

Arch Angels

Arch Angels are the people who guide and take care of the Chaos Angels, technically they are part of the Chaos Angels. Most of them are coordinating a team or "mainly responsible" for specific tasks, but of course you can contact any of them in case of any questions.
