I like that it's easy to use and allows me to customize my courses as much as possible! The only thing I dislike about this system is how long it takes for users to receive their lessons once they are created. It would also be great if you could have more than one instructor working in your account so you can assign different roles to each person who will teach students through your platform. This has been helpful when creating classes online. We've had success using EntrenarSE for our corporate employees' remote learning needs. They love being able to learn from home while still having access to all of our resources. Also, we're saving money since many people don't need to travel to attend conferences anymore.
