I know there are a lot of teachers out there who use Quia to host home-grown games, quizzes, tests and exercises. Textbooks like Ecce and LFA offer banks of questions created in ExamView to teachers. My question to the group is: do you actually use these question banks? Do you use test generators? Would using a pre-built question bank from a publisher save you time? Would you prefer to edit questions offered by publishers, or would you rather do your own thing?
