The Committee to Protect Bloggers is asking bloggers to dedicate their sites today to the “Free Mojtaba and Arash Day”, two bloggers currently in prison in Iran.

The Committee is asking bloggers to place ‘Free Mojtaba and Arash Day’ banners on their blogs and to consider other actions, including writing to local Iranian embassies.

The BBC reports that the Committee to Protect Bloggers was started by US blogger Curt Hopkins and counts fired flight attendant blogger Ellen Simonetti as a deputy director.
