Lets go with the Stats in the post header. If someone wants to track their XP in the post header they can always do so in the spoiler, and I will also keep track of XP on the character sheets I have at hand for each of your characters. If it turns out to be really important we can make it a "mandatory entry" later. It's one of the things I'll figure out as I become more familiar with Dungeo World, but the less bookkeeping we do, the more "immersive" gameplay should (in theory) become - or so I figure.
