Harvard officials announced last week that they would divest $4.4 million in shares of a company linked to Sudan. Why? They were persuaded by students who mounted a campaign against the genocide in the country's Darfur region, allegedly perpetrated by the Sudanese government. A mini-guide for the would-be activist:

Start an online petition. Organizers say they put up $10 for a domain name that allowed them to collect about 1,000 signatures.

Set up a meeting. A few persuasive reps sat down with university officials in positions of power.

Protest peacefully. Student groups dressed in black and rallied together to show their dissatisfaction. "There was just no defense for this," says Manav Bhatnagar, 20, cofounder of the movement.
