Stream of Activities
Content published in child groups is rolled up to parent groups enabling you to quickly see what is happening. Activity streams support file and photo sharing, micro-blogging, publishing questions, likes, hashtags, @mentions and more. It is common for a group to include a single activity stream to summarize the activities within a group or for the community.
Control over what content is published in the Activity Stream.
New content such as forum posts, blog posts and more can be created via the Quick Post widget, enabling users to create content without having to leave the Activity Stream.
