STM, it *was* posted at the time, but anyone trying to find the original thread would be hard pressed to locate it using the search function here. So I don't think too many apologies are required!
By the by, I've found that googling in the search terms one is hunting for and then adding 'pprune' to the end of the search string will usually get you to the thread.
