It looks like they have actually functional rules for carrying out debates, here!

So where were we on factpile?
Ah yes, there's a lot of fights for Alagaesia, and it was only recent that i saw the Potter-world vs Discworld, actually.

Is there more to add?

Also, if Potter-world fans are reading this thing, we are now fighting for our lives against the Discworlders who badly outnumber us, here.
