As for that feature, it's under investigation right now while we add new social network providers, like Google+ (in v5.1) and Twitter (in the upcoming v5.2). As we're implementing those features, we're implementing the underlying code that should make automatic posting possible. At first, we'll likely have an easy way from the front-end that an admin can manually post content to their different social network areas.
I hope that helps explain, but if you have any more questions regarding this, again, please start a new topic.
Thanks,
Alex
