Welcome to esmb! Love to see people waking up! My two cents here: you are going to spend some time dissecting Scientology and finding out what is useful and what is nonsense. I wrote a paper on my thoughts about it, which is linked by one of the two hyperlinks in my signature (the other hyperlink is the story of my experiences in the SO.)
I would never give any money to Scientology. I might be tempted to buy a staff member a bowl of soup or a beer - but that would be out of pity, not because Scientology works.
