In my opinion, the number of threads, posts and the last poster are not really needed, so if we can't have the actually useful information about how many new posts, at least can we get rid of that clutter? Also, I too would prefer you move the NEW column to the left of the group name where it is easier to pick out groups with new messages since it will align like a column better. A color variation for yes would be helpful. Also your pages have almost no white space on the left edge; it has always looked funky trying to read up against the edge of the browser window, like a page without margins.
