Hey guys
I found a new charity project called SuperDonate. They apparently use our CPU cycles to solve computing problems for organizations that pay them, and they donate the money earned to different charity organizations.
Website - http://www.superdonate.org/
It has client apps for Windows, Linux, and Mac OSX, and it seems pretty simple and straightforward to use, you register on the site, make the login on the client, choose your favorite charity and it starts working.
I'm not sure if they are out of work right now but mine isn't using any CPU power, but is taking up 500Mb of RAM. You might want to run this alongside something else to keep the CPU busy.
I created the AMD Users Team, so if you register, join us here:
