Stephen does not have a public email address and does not personally read or respond to fan mail so depending on what you're needing for advice, chances are that may not be something he would do. You can send me a PM with more information and we can go from there.
Welcome Thomas 24401! This is a fun site with lots of knowledge scattered about. If you throw a question out, there will be several here who could help. I sent Mr. King a letter back in the early 80's but never got a reply. I didn't put postage on it as I thought he was making the big bucks and would pay the postage himself. I never saw that letter again and I ended it with 'P.S. Write soon.'
