Please allow me to bring Hindupedia to your attention, which is a very comprehensive overview of all schools in Hinduism. I do this with the purpose of providing you with a means of verification of the sometimes wild opinions that thrive on this forum. http://www.hindupedia.com/en/Main_Page
It is a good and reliable source for Hinduism. A lot of what I read on this web site checks out. I especially admire how they factually report the history and origins of Hinduism based on the archeaological evidence and not the dubious linguistic theories.
