Great work, Don. I really like the new site...looks sharp and is fast and functional. The new search functionality is especially nice, both for full text (any word) searches on any or all threads and personally within your own profile against your previous posts. It also seems like there are more personalized settings for each user.
Also, I like how you can see all of the previous posts in a thread when you are adding your post to it. I notice that the header extends a little bit past the sub-header menu and forum. Probably just a formatting issue for them to fix. Also, I wonder if an icon can be embedded anywhere within your post. I tried to put a "thumbs up" icon after my first sentence, but it put the icon to the right of the Title: textbox.
