Our goal for our most recent release, 0.7alpha4, is to give a rough sketch of what Chandler will be by our first Preview release (Spring 2007). This release introduces the Dashboard, which gives users a runway view of all of their information. Users can try creating a simple task list, and can share that list with others just as they can share calendars. Users can also experiment with sending notes, tasks and invitations to others via email.
