http://www.irrepressible.info/ is a campaign by Amnesty International to stop internet repression in countries like China, Vietnam, Tunisia, Iran, Saudi Arabia and Syria, where people are persecuted and imprisoned for self-expression. Irrepressible gives three suggested outlets for participation:

1. Sign our pledge on Internet freedom to call on all governments and companies to ensure the Internet is a force for political freedom, not repression.

2. Undermine censorship by publishing irrepressible fragments of censored material on your own site. The more people take part, the more we can defeat unwarranted censorship and create an unstoppable network of protest.

3.Put pressure on companies to protect freedom of information and expression. In China, Microsoft, Google and Yahoo are supporting the government’s denial of fundamental freedoms. Act now.
