Hi, Bellybones,
Welcome to TMA - here (amongst other things) you'll find everything you wanted to know about them there stones, imparted by some of the friendliest people you could hope to meet (and I have met a few, and can vouch for them!). I look forward to your input, but please, please please try to avoid Am*zon if you can (I used to be a bookseller in a previous life....). The TMA (the big papery one) is currently (I believe) out of print, but secondhand copies are available on abebooks (www.abebooks.com) and sometimes on eBay - if you can get the limited CD that accompanied TMA for under £50, you're a genius!
Welcome
Peace
Pilgrim
