First, you can try WhoWhere, a free email search directory.
Or, if the person works at a company, you could try
searching the company's Web site, or calling the person's office and asking the receptionist

If the person
is a student, you could try searching on their school's web site. Here's a good listing of
college and university Web pages.
Also, of course,
you might just try calling the person and making up a sly excuse
about why you need their email address.
