Hey Adam,
I'd love to be part of the UI redesign. I think I can raelly help out in that arena. Right now on our instance of the Intranet I have a project open with a ticket tracker for the intranet itself. But, those are mostly technical problems, not UI items. I would assume that most of those are being fixed by the likes of Chris or Jade or someone else here.
Maybe we need a wishlist?
Scott
