      All these messages are sent to one or many clients in a single click. A Universal Inbox had to be designed to store these messages and display to the administrators.
    • Facebook posts to Pages and Groups from Liferay
      The application should be able to select & save the list of pages for which the authenticated user is acting as ADMIN in Facebook. Single Message Composer should allow creating a post in Liferay and update to Facebook pages or a groups.
