22C3 would not be possible without the help of all our participants. This year you can be a good participant by smoking less, try to protect the building from unnecessary damage and harm and buying a business or charity ticket in order to support what we do. Or you can join the Chaos Angels who run many important operations at 22C3. Without angels there would be no congress.

As usual we have opened up a Chaos Angel Registration system and we ask you to register if you want to help out during 22C3. Chaos Angels get a lot of things in return for their work. Check out the Chaos Angel FAQ.
