1. Select topics of Interest
2. Allow that topic to be updated via RSS / Email Sync via Outlook 2016
3. User can then review the topics of interest as they change
4. Or add Reader Capabilities with Windows 10 to save via Edge
5. Create Edge Pugein to Notifiy of new posts or topics related to your login in credentials for network.office.com
