Doodle is an online scheduling tool to help collaborators find a common time to meet. An organizer can set up a number of proposed meeting times and send a survey to participants who indicate availability. The free version offers scheduling and the option for a MeetMe page, which allows users to see your available time slots; paid versions include options such as calendar integration, automatic reminders, SSL encryption, and seeing who is missing. Private plans are $39 a year and business/group plans vary in price, which is dependent on the number of Doodle organizers. Ideal for team work planning and easy to use.
