If anyone doesn't know, it's neutrally written because that's what wiki is about, so mostly reads without any criticism or pro's, because otherwise it doesn't stay on there. The information seems well resourced and reliable which is good to see, and much improved from the previous edition which had an extremely vague understanding of the movement, with no history whatsoever and referred to the ELF as a UK & UK group.
Feel free to improve!
