Electronic Freedom Frontiers (EFF) has issued a challenge aimed at spreading and strengthening the Tor Project -- a network of servers and routing points that aims to allow anonymous and encrypted online communications and expression. EFF is calling on individuals and organizations to operate relay points that will strengthen the Tor network and help make anonymous and private online browsing a reality.

EFF provides a great video detailing how to set up your Tor relay as well as some helpful legal advice for the operation of such a relay.
