Yahoo enhances email security   Yahoo is adding another layer of
security to protect users.  The company is encrypting all
emails, search requests, and other information transmitted
through its data centers.  Company officials say the idea is to
make the information indecipherable to the government and people
trying to snoop.  Google and Microsoft have taken similar
measures since it became known that the government had looked at
millions of web surfers personal information in its anti-
terrorism efforts.
