Bill and Melinda will be proud of you. I pay some monthly money to NSPCC to help sexual abuse children's despite I am quite poor emigrant. Saying that. I don't think charity or philanthropy do any significant change to our society's. I think if you really want help people its better focus on politics, economics, media, science, art etc. What i am saying its better fight corporate greed then trying to always mend bigger and bigger societies gaps. Good luck.
