I created a Moodle course/web with several items, including selective release, images in the blocks, RSS feeds.
I used selective release to enable participants decide which topics they wanted to see. Also they needed to add a message to the forum and an item in the glossary to release more items.
I created a guide to give instructions for access and made the course a self-enrolment with a key.
I presented it today to 28 library colleagues. They all managed to access it and all did most of the activities.
I'm sure that they learnt more than just a demonstration.
