I signed up for this, but alas I know I will not have the time to finish. I completed week 1, but now life has just got very busy for the next two weeks. Perhaps I'll catch up a bit in week 4!
I found the first week really beneficial, so I hope that I will find time to look at some more of it. If anyone could highlight bits you think are worth paying special attention to, I might cherry-pick a little bit.
I really found the example lessons in week 1 helpful, for various reasons: some with good demonstrations of how to do it, and one particularly bad, so that I thought "oh, I know how he should have gone about that" which gave me a bit of a boost.
