This LMS King component is wicked. So full of options.
It can be a bit confusing at first, but once you get to know it, it's no problem at all.
I was using another commercial extension, but I've moved to this one because it has a very easy to use creation wizard.
I had my first Lesson online in only 10 minutes after installing it.
I had a problem with the permissions once I installed it, but that was my fault as I don't know Joomla 3 that well.
I told support about it and they identified the problem and fixed it for me in 2 minutes flat.
They said will be releasing a new version shortly to stop other users having this problem that will set the permissions for us.
All up, a great extension for the price and very good support.
