The Collaborate feature enables users to communicate together about their work. If you have the Collaboration feature enabled, you will see recent messages in the My Notifications space. You can click on the notification, or If you do not have any new notifications, you can click the link to be taken to your discussions. Both direct messages and discussion notifications will appear under My Notifications.
You can send and receive direct messages and join a discussion by clicking Collaborate along the left of your Dashboard as well.
Once in the Collaborate space, you can choose the discussion you would like to participate in from the Collaborate menu on the left.
