bookslave had a question about joining a Church of Scientology.
I answered the question in a comment, but I thought it might be of interest to the causal browser so here it is repeated:
Hey bookslave, All you have to do to join the Church is: find a Church of Scientology, walk in the front door and say "Hello." :)
About the only other thing I'd suggest is to finish the books you are reading so you know what Scientology is. It is important to understand a subject before taking any serious steps in it.
