The World Trade Center disaster has already generated a tremendous amount of e-mail spam and chain letters. As this article points out, you can count on a lot of hoaxes to be disseminated by e-mail in the next few weeks. Exercise a high degree of caution before you forward an e-mail message to your favorite fifty friends. Be suspicious. People are not grateful to receive messages filled with misinformation, no matter how well-intentioned you are. And an unsolicited message asking for money is very likely to be fraudulent. Be generous, get involved, help your neighbors and our country – but watch your e-mail!
