(Original) There are lots of organizations one can donate for the China earthquake, such as this list (Chinese) and another list (English). I think everyone can pick an amount and a charity feel comfortable. Also the wider the participation (more people give in small amount), the better. Note some employers offer match for certain charities, and there is tax deduction for donors if the charity has registered with IRS for that purpose (there is an EIN). Personally I am debating about the following two:
1. Overseas Saving Chinese Children Fundation: as name implied, the emphasis is on the need of small kids.
2. Peking Univ Fundation: Chinese, English, they said the donation will be “for the middle and primary schools in the disaster area in China. All donations will be transferred to benefit schools within a month.”
