Here's a link to one of the divisional standings pageshttp://www.nationaljuniorhockey.com/u18-midgets/standings
And no, the divisions will not mix. The conferences within each division will. I was hoping that "child divisions" within a parent would somehow be separated or easily distinguished within the parent division or something.
Unfortunately, if I assign the teams to child divisions (in my case, conferences) then the standings bracket for the parent division goes blank. It's as if the system doesn't recognize that the conferences are sub-sets of a larger division.
I have experimented with the various display options on the "standings view" and nothing seems to display the way I want it or work how I thought it would/should.
