  Tentatively interested in the premise. I’m curious, are you planning on having everyone play two characters at a minimum, or have people play their character’s past and future self, or just have each player focused on either the past or future? Also will you have two different threads? I imagine two separate but connected stories going on in the same thread runs an even higher risk of getting very confused and cluttered than normal.

Just one OOC & IC Thread.
There's no character minimum, someone can choose one character if they want. People will have the choice to play their future & past self simultaneously if they want, because the premise is the protagonists attempting to change the timeline, events that occur in the future aren't set in stone.
