receivers called in according to the strayan, page-6

Following from Balmersdog, the article mentions administrators and receivers. What is the difference in their roles? Anyone? What are some of the scenarios for shareholders? Anyone? I think I have done about 5k on this one. Bugger. Coulda been worse. Its a learning experience. I didn't do my homework and man am I being punished for it. Lesson: stay away from one man bands esp if headquartered in QLD. How many crooks are up there???
