I made of couple of simple mods to make it more specific to our field in terms of terminology. It was easy to do.
What is most outstanding is the support and the response time...it the best I've experienced with any Joomla extension provider!
This application gives our site a professional look and feel. It is not SCORM compatible, but not all education providers need SCORM.
The only suggestion I have for your next upgrade is to include a script which will generate the course title, date, user name, credit hours, and template similar to the Moodle certificate application.
Keep up the great work!
