title: Allow user to place marker on a google map
body: <p>I'm looking for a way to allow a user to place a marker on a Google map and then get the co-ordinates so I can email them to a user. </p>
  
  <p>Is it possible to allow users to do this on the fly? I've seen <a href="http://marcelpad.wordpress.com/2007/12/11/adding-markers-on-google-maps/" rel="nofollow">here</a> and understand I can do this using longitude and Latitude. So using the above method can I get a Longitude and Latitude from a users click? </p>
