The theme definitely needs some work, after the reverse threads are done...
Some specific things I've seen so far to add to the "To-Do" list:
1) Some sort of separator line between or border around the threads would be useful (as the Posts have). Rather than just going from light to dark background it also needs a border.
2) The new smileys are blurry and don't match with each other... Lack of outlines again, I think... too much "photo" and not enough "cartoon".
3) Text is squished right up against the background colour changes. For example, in the "Reply to..." golden background at the top of the replay page, you've only got a pixel or two. The forum view is like this too. More border space, please!
4) Font Size. I don't know why it needed to change.
If its too small, click View->TextSize->larger or 150% or whatever you prefer. Every page will be zoomed up by the amount you ask.
As is, it looks like I'll have to click it down to 75% whenever I come here, and then change it back to normal again when I leave, so that I can read the font at google or any other website.
The goal with font size should be to make it match the typical page, and let the user set their font scale multiplier to match their hardware and wetware.
5) Long lines in a post will stretch the window beyond 100% of the browser width. This used to only occur when Code tags were used, but URLs in people sigs (which broke under the new UBB) are blowing up some of the threads.
Having to scroll sideways is almost as horrible as having to read threads in the wrong order
(new - edit 1)
6) Extend sig character limit so we can include URLs. Especially since the new forum format has so many extra parameters.

SJ - Looking forward to the return of the reverse threads, and an "old school" theme to choose.
PS:
Looks like its time to go do damage control on my sig...
