This may have been obvious to some, but I just figured this out.
Once the new Beta Social Feed was released, I finally figured out a way to utilize Top News.
The options for Top News are: posts by Creators, posts by Featured Members or posts by Admins. Well sometimes that should not be Top News, so I turned it off.
Then there is the new RSS Social Feed, well I didn't think I would use this either because I don't want outside feeds in my Network's Activity Feed, it doesn't make sense for my network.
So...I took MY Networks "Featured Discussions" RSS Feed and pasted into the Social Feed Beta, then turned top news back on, and it works great, and makes sense. http://network.girlriders.net/
I just wish that there was a way to turn off automatically adding Creators Posts to the feed, sometimes I post silly Status Updates that don't need to be "Top News".
