Thanks for the reply LeonidS, I did find that Spaces are the best thing to use for my project. I didn't know until yesterday that it's not enough to just join a Space to see the content on the front page (assuming you add a contextual timeline feed) you have to follow that Space to see the content. Why isn't this done automatically? When you join a Space, you will auto follow it as well. It's a two step process that many users might not know from the start.

I just need users that join a Space to be able to see public content on the front page. Either when they join, they also auto follow, or if not, let them follow without the need to join first.

Another problem I face is that comments on discussions do not have the option to be displayed as Flat or Threaded. I see that on Photos or Videos, they have this option. Is this normal? As intended or a bug? I need them to have that option please.
