Not sure if it's upthread here, or in another thread, but I did find (more or less by chance), links to summaries of each week, which were linked to previous weeks, and so on, so if you were patient, you could find out what had been going on for ever such a long way back.
Unfortunately, on the current pages, they don't seem to present this as well as they used to, but with a bit of fiddly searching, one can still find the old summaries. If I can remember how I found them, I will post links again.
