Rules? For the riddle???? Well, we try really hard to PM the answer to the OP, but most , if not all, of us have accidentally posted it as a reply. But no one cares, heck half the time the answer gets skipped over. The saddest thing is when the answer is posted (correctly) and people still PM the wrong one!
Lets see, what else................ You have to have fun, and if you come around often enough, you will get to know us regulars. We have a great time here, someone almost always posts a breakfast picture, sometimes a riddler moons the rest of us. It's just a lot of frivolity!
