User Twitter News Feed

Before the Twitter Feed is visible on a User's Profile, the User must first edit their Personal Info to include their Twitter User Name. If you do not use Twitter you can just as easily display anyone's Twitter feed. For example, you could display the Twitter Feed from your church (if one exists).

Once you have updated your Profile, the Twitter Feed will be displayed on the right rail of your public facing profile.
 
Group Twitter News Feed

The same steps hold true for adding Twitter Feeds to a Group. The Group Admin must go into the Group Profile Edit section and add the Feed to the Group.
 
Once the Group Admin adds the Twitter Feed to the Edit Profile page, the Twitter Feed will now display on the right rail of the Group's Public Facing Profile.
