We've put together an online course for staff at Goldsmiths who look after course areas on learn.gold.
It's a short, self-paced tutorial that will show you how to make your pages speedier to load, easier to use and generally improve aspects of your course area.
You can view it as a guest but please email tel.gleu@gold.ac.uk for the enrolment key so you can take part fully in the forums and so on.
Let us know how you get on (the course is here by the way).
