Documentation on zone_directors, venues, regions?

I am sure I speak for most of us when I say how helpful it has been to have someone who sticks with it and does what they promise when they promised. I mean in terms of user/developer interaction. There have been countless false starts over the years. One time I was even contacted personally, as a modder, by a Sims producer, who actually left EA 3 weeks after not answering my questions he'd actually invited me to ask. Lol.
