Firstly, I'm having a ton of fun observing this process and digging into materials so huge thanks to everyone involved.

I've been perusing the "Registry of Notable Universes" and have a couple questions:

1. What are the heuristics used to select a universe as "notable"?
2. And who/what operates this filtration process?
3. What process is generating the population of universes that is being filtered?
4. How is the universe / model # derived? ( Order of discovery / generation? Determined by rules or initial conditions? )
5. How is the generation count determined? ( Most are 198, others are 49, 17.. etc. Is this because of model complexity ? Or some termination condition?)

And finally, a humble request: for the "Download notebook" link in the "view universe" page, please generate unique filenames e.g. "wm<MODEL_NUMBER>.db" . I've ended up with a lot of "base(x).nb" files in my download folder with no way of deriving the model number / resource location from the file.
