@dead_flip: Sort of off topic, but I just wanted to say I really like your set up. It is pretty cool being able to watch people play real pinball machines like we can watch people play Pinball Arcade and such.
I think we have pinball pretty covered here. Not only do we have specific pages for TONS of machines, there are also pages for things like Pinball Arcade and Pinball FX. I would imagine you could set it as the specific table you are playing? I am not totally sure how the Twitch thing works. If there are any empty pages for tables you want to use you can edit the page or just post it here and I will try and fill it in some.
