TOS support: 800-672-2098 This is the Options Advanced Support Team for TOS. I guess they are top secret because people call the other numbers and then complain about the lack of help. These folks will hook up with your computer and work with you to diagnose issues. As far as using them for thinkscript questions, some are well versed others not as much. At least they are in Nebraska and have that helpful spirit. Just no stupid questions. They helped me get legged out of a an illiquid option monster. When I asked about a real tough problem, I laughed, they sent me the the URL for StanL's 200 page guide. That guide can be found on a tab in the "Stickied 'Universe of Thinkscript' " on the start page of useThinkScript. THANKS, @BenTen for keeping it on top!
