I think we've come to a good stopping point for this afternoon. I think things are looking pretty good, but let us know if you find any problems. As a reference, I am viewing the site in DCF mode. When using the DCF view, clicking "Expand Conferences" or "Collapse Conferences" will greatly alter the way you see the board.
If you leave things collapsed, you can click on the technical sections and see all the technical forums. Likewise if you click on any of the other conferences, they will expand for you to view the forums within. Clicking "Top" will take you back to the view with all conferences collapsed.
I've experimented with a number of options and I think this works. Please let us know if something doesn't.
