There's really only three that are intended for non-pinball stuff, and one of those is private. My "tltljlp spouts off" usually is pinball related, and the Back Fence is loaded with humor, which is never out of place. The Soap Box is pretty much like vpf's old Debate Central. Just like to give folks variety. If we lumped everything together, the humor might get lost among the rants and raves, which would be a shame. And no, Rodgz's Echo Chamber isn't for hard porn, or for any porn, which isn't allowed. It's simply a private area where you don't have to be on your best behaviour.
