Recommend It is a content plugin that recommends articles from the same category. It uses jquery to nicely slide in the recommended articles when the user reaches the bottom of the page. When they scroll back up, it disappears again. You can also close it for good by using the close button and it will not be shown again until the page is reloaded. There are a number of built in features. You can see the parameters listed below.
Recommend It works on core Joomla content, Zoo and with K2.
