A Doomsday for Everyone

I am thinking of making a doomsday future TL that would allow everyone to create their own small post doomsday nation, similar to the Doomsday 1983 TL on Alt history wikia. The TL would begin in 2010 where swine flue mutates and becomes far more lethal. By 2012 90% of humanity is dead, and the planet left in chaos. Create your own nation with a history section detailing how you'd found it after surviving the apocalypse.
