if you have any questions about scientology ask away, i have put alot of time studying scientology and could answer most questions about it.
One thing ive seen posted false already here is that L.Ron Hubbard started the church, In fact there was no scientology to start with. He was selling his dianetics system and as it grew people who were using dianetics formed a group to discuss the system and talk about what things had happened to them.
At this stage there was no religious aspect to the group. It was purely a mental health type group that could fix your problems. After a while people started asking questions to L.Ron that werent contained in his dianetics system. He developed his religious theorys at this time and put them out to the dianetics users and called this new aspect "scientology" It caught on to the dienetics users and this scientology and dianetics became under the banner of scientology. Then they changed its name to the Church of Scientology.
The need for a L.Ron to start looking into a religious aspect came from people using dianetics and having "religious type experences" and asking for more.
Due to popular belief, there is no proof that L.Ron ever claimed that he would start a religion to get rich. Though who knows. I once read a quote from his son who said his dad was "the biggest conman on the planet". his son even had to change his name to get away from being tied to his dad.
and ways, any question feel free to ask away.
