The global web blog community is being called into action to lend support to two imprisoned Iranian bloggers. The month-old Committee to Protect Bloggers’ is asking those with blogs to dedicate their sites on 22 February to the "Free Mojtaba and Arash Day." Arash Sigarchi and Mojtaba Saminejad are both in prison in Iran.
