On the Atlas Dashboard, click View My Tasks to jump to the bottom of your browser dashboard to see any open Tasks, that are assigned specifically to you. If there are any incomplete Tasks in the system assigned to you, you'll see "View My Tasks" at the top of the page. On the Task Dashboard, you can sort the list, edit or delete any of the Tasks, and mark them complete using the Actions dropdown for each task. Once a Task is marked as complete, it will be removed from your Dashboard - but you can still find it in the Task Search and/or profile.
To add a new Task (to yourself or to assign to others), you can click the Add a Task button. Click here for more details on adding a new Task.
