I would say this is one of the most important components for Joomla and I have depended heavily on several on a busy ecommerce site. Essential. Hats off to you for the clean and professional interface.
Good support from the developer. They answer questions very quickly and have committed to working out a minor issue of needing to refresh the page to have the "buy now" button change to "take course" after a purchase. Other than that, it works seamlessly for ecommerce applications. For non-ecommerce applications, the component does not have this issue and seems to work perfectly.
It is very simple to control from the backend. Loading course materials, quizzes and questions, and other control parameters is a snap. One great value to this LMS is its integration with Virtuemart. I am running Paypal Pro with no problems.
I am happy to see that this LMS is back!!! Joomla is a great CMS and this is one of the only LMS's designed for Joomla. Some very minor knowledge of HTML helps to customize the user interface for the front end. Essentially, there are a few template files that can be easily modified to give the LMS the desired look and feel. On the wish-list, perhaps a more streamlined user interface that has less pages to click through to access course materials, certificates, and such. The other wish-list item would be a log of the questions that were answer right and wrong on each quiz taken per each user. I recommend this LMS look forward to seeing it develop with Joomla.
