I've been using Mangaroo.com to start prosperity challeneges for years. But it seems to be down. I know there are many other sims randomizers that create one sim at a time, but this one is the only one I've used for creating up to 6 families at once. Are there other sites or apps that create large numbers of random sims all at once for challenges like Prosperity?

Also, does anyone know whether Mangaroo is just temporarily down or if it's gone for good? I just used it 2 weeks ago, and there seemed to be no "goodbye" message, so I'm hoping its just a glitch.

Well, katrisims' Sim Randomizer comes to mind, but it'll only randomize up to eight (8) Sims in one go.
