I would love to give LMS King an excellent review. After being a Moodle user for many years, it has all the features I was seeking in a Joomla integrated LMS. BUT. The support is poor at best. Even as an experienced user of LMS systems, the structure of the system is complex enough that I require training to use it properly. The documentation is weak (I can deal with that, and would happily contribute to it once I get to that point). But I posted an urgent request ticket (#652398146) on their website 5 days ago, and have yet to hear a response. To me, that level of service undermines the excellence of the software itself.
Andrea, your support ticket was replied to 27 minutes after being submitted but the reply bounced because your mailbox was full.
