I was checking out that link you posted and realized their own group had a short life. Maybe it was because there are just soooo many places in their RP. If you were to re-create this a bit, would you consider narrowing the sites of actual RP down? I know there are a bunch of places in Fallout, but to cover all that would almost be extreme -unless you have a 'whole' slew of people to get a sub-thread created.
Really, I was just interested in popping in to see how detailed this would be. It sort of in the beginning phase so I'll just wish you a 'good luck'. (That may sound a bit foreboding, but I'm not the incredibly knowledgeable person to turn to for world building... just interested enough in peeking inside!)
