"With the Internet, it doesn't have to cost a penny to make a difference," says Daniel Bennett, co-principal of e-advocates and co-author of The Net Effect: How Cyber Advocacy is Changing the Political Landscape (Capitol Advantage) with Pam Fielding. "The Internet can increase your political capabilities. And you'll find kindred people." Available services include online newsletters, chat rooms, bulletin boards and e-mail campaigns.
