Since this is for a great cause I thought I would bring up the upcoming Mario Marathon that starts June 11th at 6:00PM and will run for a week straight (168 Hours). They will be playing through a lot of the Mario games while raising money for ACT Today (http://www.act-today.org/).

TheSpeedGamers have been streaming video game marathons for over a year to raise money for various charities. In total they have raised over $140,000 dollars and played 17 marathons. They have raised over $50,000 in their week long Final Fantasy Marathon, and have made multiple news appearances. This upcoming marathon will be for ACT Today. This charity provides grant money for families that cannot afford or access the treatments their autistic children need.

During the marathon we will have multiple contests to win various prizes. Some are contributed by TheSpeedGamers' gracious community members

For more information you can go to http://www.thespeedgamers.com and is also where the stream will be broadcasting.

There will be special guests, ProtonJon,(Let's Player) ChuggaConroy,(Let's Player) Steve Wiebe,(Great Donkey Kong player, and first person to ever get 1 Million points in Donkey Kong) and Kari 'Essentia' Johnson(Known for her Final Fantasy Speed Runs).
