The site looks slick, if a bit white and bright but here is some feedback from my point of view (with attached screenshots):
Borders (left and right): Not sure if this was always the case, but there seems to be a lot of red either side of the main pane. Is there any chance of reducing the amount of red border so that there is less wrapping?
New Posts: Previously unread new posts were displayed in bold and once read, they no longer appeared in bold. Now, everything seems to be the same font style.
• Different colours for different columns on some threads
• Full titles not always displaying
• Time of post of last message not displaying
Posts: There seems to be a lot of unused space for each post. In the example screenshot, I have highlighted in red all the space available but for whatever reason the post is the same size. I think the frame of the post should adjust to the amount of content. The avatar seems quite big too IMO.
Footer: The text at the bottom is not very legible in its current colour.
