There are some courses I am interested in, but start at a bad time for me. Like the introduction to philosophy course, which I wouldn't mind trying out.
It starts in September, which is when my 3rd and final year of uni starts too. I don't know if I want to spread myself that thin (I really do a hefty amount of research for all my papers), what with homework with the kids, all the regular real life stuff, plus the year that makes or breaks my final uni results.
If I can find one that I like for over the summer, then I am signing up, since I'm only doing pre-reading for my modules, meaning I will have time.
Thanks for the link though, I have no doubt everytime I have spare time now, I will be filling it more productively than staring at a wall, or refreshing CEMB and FB.

If your internet connection is reasonably good, you could sign up for the course and then download the video lectures, and watch them in your spare time or later in the year when you are less busy. You will miss out on doing the exercises and mini exams, or interacting with other students on their forum, but I guess that's no big deal if you are just curious about the subject. That's what I did for one of the history courses because I couldn't keep up. Every now and again, I'll watch a lecture if I've got some time to spare.
Also most of the courses will repeat at some point, so even if you miss out on it this time, there will be another
