i agree tessa, i was just wanting to hear from others how they relate to the topic personally. The whole topic in chat made clear that there was a wide spectrum of definaitions, but at the same time there were a couple of very ahem "vigilant" people in the room who believed there was a very defined definition and anything either side of it should not be termed pe or tpe. This seems like a very limited point of view for me and so I htought i'd put the question to the forum for feedback.
