That is an old mod that has been unsupported for years as a matter fact it was created before the resource manager and never moved from its original thread to the RM. search vietvb or vienvb or some similar username. If I recall correctly that is actually version two and it was removed/deleted for some reason or another. Although I do believe version one is still around in a thread somewhere but not in the RM.
It would be awesome if a trusted developer would create an advanced forum statistics plugin of their own since there really is nothing similar that isnt outdated or maintained here anymore that I'm aware of anyways.
