The Serving Mathematics project has money until the end of March to fund new features for the quiz module. Many of these features are not mathematics specific but would be useful for any quiz user. I have summarized them in the quiz forum and in the developer wiki.
I am cross-posting here because I would like all developers to know that there is some funding available. Anyone with good knowledge of the moodle code and a few days to spare over the next two or three weeks would be welcome to help out.
