I’ve moved a couple of categories for campaigns which are no longer functioning - Dry Spell (Chicago / New York) and Hogwarts - to the Archive Category. There were a couple of other candidates - Chimera, Medusa, and Fallout - but its not quite settled that they’re dead yet (or rather, people keep talking about reviving them).
If these campaigns (or any of the other ones) revive, we can move their groups back quite easily.
