The characters you selected in this thread are for the newRPG, which is where you should be starting. The RPG archive only has threads from the old RPG (which, incidentally, the finale is still happening) so there's no history you need to concern yourself with since the new RPG is a reboot. The wiki also hasn't been updated to reflect the new RPG yet, currently referencing the old continuity.

I was thinking that too, though after having a look through the archive, it's surprising more daunting of a task than I thought. Especially when you get closer to the threads dated from 2001-2003. It's tricky figuring out what goes where.
