I want to use questions from the question bank for practice without all the hassle of the quiz. So I've drafted a dataform field which accepts as input a question id and displays a link to preview the question. The result is a sandbox which can be used, for instance, on the frontpage to allow guests to play with questions. If the questions know how to random, the user can restart to get a new instance. This may be particularly useful for practice purposes.
Tim, is there any reason to not use the preview in such a way?
The following illustration shows a dataform on the front page and an entry which displays a link to a question
The link opens the question in a preview popup
