When you submit an icon for the community, roll +Art.
This community needs an icon, and sadly, there's no obvious logo to go to as many other communities have.
So: I'm throwing it out to you. Submit what you like, and to be honest, this will be me picking, influenced a bit by the votes.
Something as simple as a PBTA in the Apoc World font would be clear, but I'm very open to people who have positive Art stats...
