Allowing users to add markers to google maps and getting the coordinates

Question

What i want to do is embed a map on my website and allow users to place markers on it (also if there is a way to control how many markers a user can put on the map?) and i also want to get the coordinates of these markers once they have been put on the map. From the documentation that i've read for google maps javascript api V3, i can place markers on the map myself, but i dont see a way to let users put them up on the map. Is there a way to do it?

Source: http://code.google.com/apis/maps/documentation/javascript/events.html Scroll down to accessing arguments in UI events.

var map; function initialize() {   var myLatlng = new google.maps.LatLng(-25.363882,131.044922);   var myOptions = {     zoom: 4,     center: myLatlng,     mapTypeId: google.maps.MapTypeId.ROADMAP   }   map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);    google.maps.event.addListener(map, 'click', function(event) {     placeMarker(event.latLng);   }); }  function placeMarker(location) {   var marker = new google.maps.Marker({       position: location,        map: map   });    map.setCenter(location); }
