I just updated the headers (getting rid of the bright gray on US.c and color matching it with the active2 layer), and edited the "Go to last post" icon, so it's black on UB.c and white on us.c (so you can see it).
Edit: And updated the postbit head.. the little arrow below the words "Private Messages" that comes before XXX Forums > General Topics.... etc. at the top.
Edit: Fixed the timestamp colors so they're visible now.
