Ezycourse is an absolute pleasure to work with even though I have zero knowledge of LMS building.
It's difficult to pick out a highlight as the whole experience is outstanding but I have to mention the phenomenal customer support. In most windows of the interface, there is a chat button bottom right and the response speed is amazing. I don't know if Shakil ever sleeps but I have never waited more than a few minutes for a useful and helpful response. Forget convoluted ticketing systems where they get back to you in a day or two.
If you are looking to create a learning platform then honestly you need look no further!
