In particular, August 11, 2001 seems to be the last time The Wayback Machine saw a non-404 page.
Personally, I'm suspicious of that FAQ as it seems to contradict what I've observed in my games, so far. I'll list information that seems to be missing or wrong.
1) The Fate Structure capacity multiplier seems to depend upon the live EMBO population, not the SOUL population, with the x1 --> x2 threshold at 120,000 living EMBOs. It's in your best interest as Demiurge to have a quickly-growing EMBO population (both for this reason and also because more EMBOs means more natural deaths per year).
2) The FAQ speculates about Ad Infinitum Siphons. What I've noticed is that it's possible to not have enough Siphons to power a realm, in which case your Mapview will show you that some of your Afterlife isn't charged.
Individual Siphons provide charge according to how many Rocks the Siphon is adjacent to. Diagonals count as adjacent, so theoretically, a Siphon can be adjacent to as many as 8 Rocks. Further, the progression is exponential by factors of 2.
1 adjacent Rock: 42 Qs
2 adjacent Rocks: 84 Qs
3 adjacent Rocks: 168 Qs
...
8 adjacent Rocks: 5376 Qs
I don't know, precisely, what a "Q" is. (I suspect it's enough charge to power one tile, but I haven't tested this. Each realm is 100x100 tiles, including the border river that surrounds all of your Heaven or Hell.)
It's worth noting that TAPPED Rocks will conduct Ad Infinitum charge (except diagonally). So, in the case where rocks surround the Siphon, you only need to run the road to the Rock, not all the way to the Siphon itself.
