Well, I finally got around to opening the computer and trying the next module and what do you know? The site is down for a few hours. So I'll have to try again in a few hours - or days.
I suppose I could go back to the last module and have a look at some of the thousands of links that I haven't visited. I've been inspired by some of the other bloggers doing this course, they have found all sorts of fun things to do. The downside seems to be that they are spending hours on the internet finding them and playing - I mean working! I will have to see what I can do.
