Not to derail or sidetrack the current discussion but I just noticed that, despite being in Britain for the last couple of months, I'm still somehow ranked as the 11th most frequent poster in this thread. That is so very very sad. Or it is a perfect example of how much time we PhD candidates have on our hands because, unlike the rest of you, we so rarely get down to doing any real work.
I now return you to your regularly scheduled discussion.
