RSVME is a free survey tool that integrates with Outlook and other email packages, and makes obtaining feedback from people a snap! You can quickly and easily put together a survey on any subject, from the best time for soccer practice to who's bringing what food to a party. Then select names out of your address book you want to send the survey to, and send. It's that simple! As your friends get your email and answer your survey, you get the response back in one simple-to-read report.
