Biggest thing I want, is an easier way to find members. W/ VV2 I know you added something to sort from sickest/age etc, but you still had to go through a lot to find something. Maybe have specific groups. Male/female, the skills they are building, age range, sick.
As for the mothers nursing for two years, come on, it makes sense. Men can't nurse. It's a deserted island, they don't get bottles.
I think having a tribe with a culture of monogomy would be nice. But I won't hold my breath for it.
