Just so I understand this... to show up in the jam feed, do I need to rate the game and/or write a comment on a page specifically to do with the game's entry in the jam? Or if I just rate any game that's in the jam, even if I don't know about the jam at all, does that rating show up on the jam's feed?

This is all a bit confusing: I can see the feed, but there's no way to get from the feed to "the place to do more of these ratings"! And if I start from a game's page, I can't find any of the ratings and reviews in the jam's feed anywhere on the pages to do with the game. So I'm a bit lost!
