Is there a way to show group postings in main section of site?

I'm using the Social theme with BuddyPress.
In the home-center widget, is there a way to show the post from the various public groups?
If not, I missed how to allow members to create posts without turning on the "Author" tab?
I'm trying to replicate the Facebook "What's on your Mind" status portion in the home-center.
Thanks, we're looking forward to using the site with your themes and plugins.
