If you buy only ten books this year, buy ten copies of RT Essentials!

Ok, I'm kidding. I wrote a couple chapters for this one and it should be out any day now. Hyperbole aside, I think that for people who are currently using RT or considering it, it will be very helpful. And especially if you've ever considered customizing RT but couldn't get what you needed from the RT docs, this book should help fill the gaps.
