Online Classes

I've just finally finished my online nutrition class and I'm not sure how much I'd ever want to take one again. I'm glad I did it, but with all the confusion about where things are and what they are and not having the teacher always respond to your emails? No thanks. I just this last weekend found out about a huge project for that class the teacher claimed to have emails us about... still haven't found it. The one fun part was having a British partner for the group project! Has anyone else taken an online class? What are your thoughts.
