Looks good (although the quick reply box - including the font used - don't seem to match (see http://easycaptures.com/5802118223)

Also, the new posts search doesn't show me which threads I'm subscribed to (and it took me a while mousing over things to realise that the replies count was the "first unread post" - perhaps a title="Go to first unread post" would help?)

EDIT: Raised as #4428 and #4429
