My RNG idea was basically that, rather than asking for rolls, the mods could impose rolls based on what's going on in the thread. (I believe I was listening to an arc of TAZ: Amnesty at the time, so I had Monster of the Week Mechanics on the brain). Obviously that gets unwieldy since it's a lot for you guys to pay attention to and not every thread is going to require a roll.

i could see some sort of hybrid mechanic coming into play? But again, it's a lot and I'm not sure how it would be implemented.
