The Further Reading section of the Pool School has all broken links coming up with the vBulletin message that "No Thread specified. If you followed a valid link, please notify the administrator". The links are not pointing to the specific threads and are only pointing to a name at the highest level (i.e. no "content" sub-directory nor "threads" sub-directory with a thread number preceding the name).
By the way, I like the standard editor better as well, so thanks for putting that back as the default.
