Doodle: About: "Doodle is a Web-based service for finding suitable dates for group events (e.g., an appointment, a conference call, a family reunion, etc.). Doodle is particularly useful to people who do not use a common calendar or groupware system.

In addition to scheduling events, Doodle also supports polls in general. That is, groups can also conveniently decide on options other than dates: the movie for the next movie night, the logo of the new Web site, the restaurant for the Christmas dinner, etc."
