Irrepressible.info is a new campaign from Amnesty International, which aims to fight censorship of the Internet.
You can sign the pledge on Internet freedom, and you can put a text box on your site which reproduces passages that some governments have banned their citizens from seeing. I have placed such a box on the right sidebar.
Scroll down and click on the text to find out where it came from, and who banned it.
Freedom of thought is a human right - one might say that it's the human right - and the Internet is an important tool in winning and maintaining that freedom.
Support the campaign. It'll take two minutes.
