Funny how none of the PRISM companies support this initiative. However, say, Google's participation would highly increase the awareness of the cause. But all they came up with are copycat press releases to deny NSA revelations and a non-significant motion to allow for full FISA orders statistics be published (which was denied, incidentally).
just heard about it 3 days again but to organize something in Austria, you usually need some weeks of preparation. Hopefully we can support you next year here in Austria as well.
