Ultra Recommender is an easy to use and full featured website recommendation program. It is easily customizable to match the rest of your site. You can use a link, an image, or a form, as can be seen at the demonstration page here. Users can click an image or link, or fill out the form, and enter up to ten email addresses at one time. A separate email is sent to each address, and, unless the form method is being used, they can also add a personal message. The format of the email is also customizable, allowing you to add whatever you wish to the head and foot of the email. The follow-up page that the user is brought to once they send a recommendation is easily customized in any html editor. You create the page, insert some tags as instructed in the installation file, and you're done. It's free!
