People in Iran are Speaking Out, Taking a Huge Risk, Let's Support Them
Go to Zizox's Flickr page and tell her how much you support her and encourage her to keep taking photos and expressing her art at this momentous time.
Here you can watch: #IranElection at search.twitter.com.
If you have a Twitter account, you can "Retweet" messages that you think are of particular value. You can turn your profile pic green. You can spread the word to others that you know.
Even if you don't feel comfortable participating, it's really worth watching first hand to see how Twitter can be used for this kind of thing... even if you are just trying to figure it all out.
Another place to "watch" and send people to is Flickr... Just search on Iran Election.
