If you’ve connected with other members of the Sales Enablement PRO community, you have the ability to message them. You can access your messages in one of two ways. First, in the profile drop down (accessed by selecting the dow arrow in the top right corner of the site), an option will be available entitled ‘Messages’.  Selecting that option will take you to your Messages inbox, where you can view all messages you’ve sent to or received from other members. Second, you can navigate to your profile, select the ‘Connections’ tab, and select the ‘Message’ button for the person you would like to message.
If you have unread messages, a notification badge will appear next to ‘Messages’ in the profile drop down counting the number of unread messages currently in your inbox.
