Can someone explain to me how certitude works?   Does it only accept coordinates or does it accept "other answers" too like keywords and such, and then it gives you the coordinates?  (I heard that such a thing might exist...)   I tried to log in to the certitude site and create my own certitude to see if it only accepts coordinate answers or if it accepts keyword or other weird stuff, but unfortunately the site won't recognize me. "unexpected error"  :/
