Having mongered for many, many years, and been a member of just about every Forum over the years, there are a few things that stick in my crawl when guys comment or ask questions. First, do your homework. That is what a "search" button is for. There are more than enough Reviews on Tai Chi to get a good idea of what options there are here or at any given spa. Second, don't ask for information if you provide none. I have posted almost 300 reviews on rubmaps.ch, and over 100 on spahunters.com before it got shut down. I freely give info in my Reviews because I appreciate those who have given me similar info over the years. Third, after reading a Review, and if you have some specific question, use the PM to contact the Reviewer. But don't contact me unless you have a proven track record of reporting. I can only gauge your credibility by what you write and how often. If you do these three things, you will never ask the kind of question that started this thread. To those who have shared valuable intel over the years, thank you. To those who never provide intel even though you make spa visits, I hope you will reconsider.
