I noticed your thread earlier!
I've been thinking about it. Nothing as yet aside from the usual fear/trick or treat ideas, in light of it being October, but I remember that was done some time ago. Planning to look through and find things so it's not just a copy. Although, a repeat might be good for people who didn't get to join in last time, or for those who want to try a different angle this time around... Have you thought of anything?
