Signal Angels (formerly called Mission Angels) facilitate communication between the people watching the live streams and those in the lecture hall. Signal Angels will be talks to relay questions that arrive via IRC or Twitter.
Signal Angels during the talks always have the best spot in the room, up front and close to the speaker in addition to a wired network connection.
Signal Angels will also roam around the 28c3, helping show off what's going on at the 28c3, finding people who are offline and generally making sure that no nerd gets left behind
Signal angels must:
- Have their own laptop (with webcam if roaming)
- Have a working knowledge of IRC and Twitter
- Be comfortable asking questions and working with the Herald Angels during a talk
If you're interested in asking a question during a talk or getting in touch with the Signal Angels, look at the no nerd gets left behind article.
