What fun to convert a course from 1.9 to 2.3 without too many wrinkles. To play with new features of Moodle (blocks!). And to create an image interface to link to each unit (something I've wanted to do for ages). http://tinyurl.com/demomrslo
Many thanks to Russ Willis of GlobalClassroom for helping me work out the Moodle 2.3 surprises.
