The Social widget enables developers to add capabilities of Social to external applications. Since the widget is hosted on your Social server, it can display personalized information. An activity stream of the most recent user actions will display to the group's members.
There are two options of the Social widget that provide different levels of integration and information.
The basic version of this widget is an iFrame. The more advanced version is a button you can insert in a page; this will display a small pop-up with information about the space.
