The Speed Gamers - Raising money for charity

I couldn't find a topic about them so I though i'd start one. I was just wondering how many of the giant community know about these guys?
 
If you don't know anything about them they are a bunch of guys who stream marathons for a series or genre of game for either a weekend or a full week. They do this to raise money for different charities. It's a really good idea and they deserve more attention. So if you have the time check them out for a bit, maybe donate if you can and help raise awareness for these guys doing something good.
