So someone has already created a Review Resource but wont release it, so that being the case can someone try to duplicate this one below. I am willing to pay a good amount of $$$ and have others willing to as well!
Tenants has a business directory add-on that he says will get review functionality in the next update. While it has started out as a business directory, I don't see why it can't be used just for general reviews as well. It integrates into the rest of the forum in the same way as the reviews on adminextra.
