OK, regarding portals, they now work better than ACS Classic 3.2.2, where they were somewhat broken due to the typical aD reasons (original assumptions broken by new code, with no testing to catch the problem).
aD is working hard to fix their systemic QA problems, BTW, let me make that clear while I rag out on them for past habits :)
Intranet's been patched up by me over the weekend, probably by others in weeks past, and Dan's port seems essentially solid. I played with it for a couple of hours on the plane and things mostly seem to work. There are small oddities, like people are never flagged as project leaders on the employee admin page even if you assign them as project leaders (and they do show up as project leaders on the project page). This appears to be an ACS Classic problem, not one introduced by us.
If you don't slight eccentricies like that, it appears to be working fine.
