The best thing about memorizing your credit card #, exp date, and security code is that you can make spontaneous donations before any voices of fear or realism intervene.
I just got this email from AVAAZ:
As we commemorate the 50th anniversary of the 1959 Tibetan uprising, a blackout is descending across Tibet. Foreign media are being detained and expelled, armed troops are patrolling the streets, monks are being arrested, and phone networks are being cut, closing off crucial information channels to the outside world -- click on this link to donate to send crucial technical support and equipment to Tibetan civil society groups, such as Voice of Tibet, and help protect Tibetans from further human rights violations.
P.S. Consider donating to support organizations like Voice of Tibet at this crucial time. They need our support now more than ever. Even a modest donation will go a long way
