Two fonts are used to distinguish what I say and Perth Group's texts:
The current font for what I say
and this other for the Perth Group's texts.
What I say is only my own opinion and it does not necessarily coincide with Perth Group's position.
Besides, Perth Group's texts could be reduced and the bibliografic references removed, in order to make easier their reading. But it will always appear the original link, so you could read the exact text and the references there.
