Follow the below steps to create a task in your task manager.
Step 1:  Go to My Tasks
After you log in to your account, click “MY TASKS” on the left-hand toolbar and click the green “NEW TASK” button.

Step 2:  Complete your task information and save
Complete all the fields in the new task dialogue including task title, priority, the assignee, description and other information.

You can assign your task to anyone in your address book and include any other interested parties as “followers” to keep them in the loop with any comments or related email notifications.
The “Approved by” field allows you designate a contact responsible for signing off a task. However, using this field does not restrict the task creator, assignee or followers from dragging the task to “DONE”.
Sub-task checklists can be used to further divide the task up in to pieces to provide further detail to the assignee.
You can also add any related attachments via the “ATTACH FILE” button.
When finished, click the “Save” button.
Step 3:  Save your task and notify assignees
Once you have completed your task information, click the “SAVE” button to send email notifications to the assignee and other selected contacts.
Any related attachments will also be included with the email notification.

Note: If you assign a task to yourself, no email notification will be sent.
