The Club Nintendo thread is mainly people talking about what they're currently playing on a Nintendo console and some trailers and tweets. There aren't many longer discussions. Those happen in separate threads because every single Nintendo game gets one.
About thread creation.
It's way to tedious, I basically keep forgetting how to do it because it's all a big jumble and then I just give up. I did make a few threads but it sometimes just doesn't feel worth it.
It should be easier to create a new thread. I bet more people would do it then.
