Al-Qaida recently asked supporters to submit questions on the Web to the terrorist group. More than 2,000 inquiries posted on a message board are to be answered by Osama bin Laden's deputy, Ayman al-Zawahiri. Many of the questions were from women asking about their role in jihad. A substantial number of people also asked when they would see another attack in the United States.
