NOTE 1: for this to work you will need to create on Joomla contact for every author and don't forget to select the correct user for every Joomla contact form NOTE 2: After you create the field, go to item edit form and check that it works properly. This field must appear as a single entry in a select box. The single entry will be the title of the user's contact form. After you save the first item, goto frontend and check that it works by clicking at the created link (author's contact form should open). If it fails, double check the above steps and check that you have created a Joomla contact for the author.
