There has already been a huge amount of interest in the US. Over 6,800 people have registered on the AIUSA website, pledging to write over 185,000 letters, and there has been support from different blogs, as well as on Facebook. There are even resources available in Spanish.
If you have any doubts as to whether or not your participation can really make a difference, all you have to do is check out this letter from Sami al-Hajj, a former Guantánamo Bay detainee who was featured in the 2007 Write-a-thon, or read about some of the other successful cases.
Just because the Write-a-thon starts today doesn’t mean it’s too late! All you need is a pen, paper, stamps, and the desire to change someone’s life.
