I've finished the major components of the forum upgrades. I'm seeing about a 120% improvement in page display time. (This may take another day or two to filter out to everybody via the CDN.) If you're having any problems loading the forum pages or seeing any unexpected display artifacts, please let me know. The JP Software blog is also loading about 70% faster, though that wasn't a significant concern anyway. The next step is to implement the CDN on the web site.
