If you still have the old exam-relate content archived somewhere, it would be extremely valuable to restore it. Exam candidates had become accustomed to being able to search the archives to help them with tricky points as they studied. Since the old forum died, I’ve heard from a lot of frustrated students who missed that study aid.
More than that, if they can’t restore the old content, it would seem foolish for the actuarial community to continue to use these forums. What’s to stop them from deleting all the information all over again in a few years out of convenience?
