My University uses Moodle, which is also TERRIBLE. I do all my grades and such in Google Docs, since Moodle is a UX nightmare. Something as simple as entering grades in Moodle requires a lot of clicking around for each grade. We have multi-page documents describing how to perform even the most basic tasks, they require constantly clicking and going to new pages of indiscernible icons. Menus are impossible to navigate without help.
