I would like to see the discussion boards expanded. On some of the busier one (Brainking.com and Feature requests), there is often LOTS of posts that tend to hide other posts. Especially if the "New" posts don't all fit on one page.

Each discussion board needs to be threaded. That is, all of the posts for a specific topic are grouped together. You can collapse/expand individual topics. This would be similar to a real forum. Here is a freeone. You can see it in action here.
