ComputerWorld NZ has the details of this new coalition (via Michael Geist). So far, the public interest groups have just set up a site to share information. Among those groups is the Creative Freedom Foundation which worked successfully on the black out NZ campaign to defeat some draconian copyright amendments.
We need more of these sites and coalitions. Perhaps a “plurilateral” coalition to meet ACTA with equal and opposing force. I also think we need to organize public action as ACTA appears to be on a relatively fast track.
