I've tried a lot of course sites ... most of them overcomplicate things and still somehow miss essential feature. Seturon is visually welcoming and super easy to create and visualize your course. Probably what I like best is the assignment function, which isn't overcomplicated, but allows me to receive and review student work quickly. There are some workflow and interface rough edges that can bee smoothed over, but the team is very quick to respond to these.

Its the first course app that doesn't make me want to pull my hair out every time I login and see a menu full of stuff.
