well, I am doing something with a few friends for the good of kids with cancer. last year:
http://www.stbaldricks.org/every $100 somebody pays me i pledge to raise $1 real dollar.
I will post a new topic when the time gets close enough to do this again (mid march)
EDIT:reply to me if you are going to do it. Ops+, please don't just generate money and pay me billions of dollars. That would be nice, but I could never keep up with it in real life.
