Sorry, there will be a delay in terms of my continuing support with the hub. This might mean it will take much longer to put together, the reason for this is that we need to shift and sift courses...and there appears to be disagreement about this in terms of what exists already.
In the meantime do refer to Moodle.net, there are some courses underneath the demo button, not all. And you still have Mount Orange, which lets you see the same courses in Moodle.net but you can navigate in different roles.
