I don't know if there's an example on his site, but I've got an example of a 6.1.1 CatoBase for a league with a 29-year history. If you're interested in finding out a little more about CatoBase, you can find it
here.
The draft history feature is especially cool, and I like the addition of managers to the team history pages, too.
This is my solo fictional league that I'm sporadically writing about over in the Dyasty forums, so I hope this demonstrates that CatoBase isn't just for online leagues.
