Feed set up

I am creating the feed for the Daily Theme. I have BP and MUWP. I saw somewhere that a contributor can add content. How do I set it up so only paid members can post to the feed in their categorie on the main page? I went to install Supporter Plugin. Do I need membership also or any other pluging to have this feature? What would be the best simlpest way to set that up?
Main feed by paid member to their certain category.
