Yelp needs to add a function to allow users to notify Yelp when a restaurant ceases to exist. Last week Yelp offered to make a reservation in a nearby town at a place that closed a year ago; I accepted. Town was busy and we were lucky to get a seat at the bar of a new place or wed have gone hungry that night.
Users should also be able to add restaurants and report places that are not correctly located on the map.
