Exactly what the title says, really.
This is a post to remind you that the October plot starts in a few days, specifically October 1st. There will be an IC post that day to signal the start and characters will be encouraged to use that post for getting their bearings and so on like they did back when the Machine crashed.
The original plot detail post is
here! You can still sign up characters as well. Remember, if you sign a character up for the 'surprises' category, they are already in the running for 'choices.' It's just adding a few bonuses as well.
As just a random aside, remember this is a month long plot. Characters will also be encouraged to have fun with shelter finding and the like.
