The Message Stack is a group of Drupal modules that enable cutting-edge social networking and user engagement features such as activity streams, notifications, subscribing to a particular content, etc.

Amitai Burstein, Gizra's CTO and the lead maintainer of Message Stack as well as Organic Groups 7 and Entity Reference modules, will discuss the core modules that make up the stack: Message, Message Notify and Message Subscribe - their architecture, different roles and how they work together in real world scenarios.

Message Stack is used within Commerce Kickstart to provide robust functionality for administrative back-office users, like order history and notifications. Its extraordinarily flexible design can also be leveraged to construct engaging eCommerce experiences. Bojan Zivanovic from Commerce Guys will join Amitai and discuss the innovative ways that Message Stack is integrated into Commerce Kickstart.
