We’re running on the newest version of WordPress now.
I have also installed WP-Super-Cache in an attempt to reduce those pesky CPU Exceeded errors that keep happening. Supposedly, for anyone who is a logged-in commenter there will be no visible difference. Leaving a comment will update the cached page immediately. Keep an eye on the sidebars, though — those may not update instantly, not sure.
Let me know if you see any problems.
