The collaboration feature allows you to share your task information with other associates. This is beneficial for tasks that involve multiple people. To collaborate on a task, simply click the "Share" button when creating a task and select the individuals with whom you want this task to be shared, or enter in their e-mail address in the second box, and click "Share". You can share individual tasks, entire projects, or complete roles. When your associates have completed and updated tasks that you share with them on their own To-Dos List, that information will be automatically indicated on your to-do list! You pick and choose what to share, so you don't have to worry about everyone else seeing all your activity.
