A plea to all the nebiews posting dumb questions here ("What is HoT and how do I get it?"): go over to Mendax and read this class guide: http://mendax.org/?p=25
It's a very well written piece that covers more than the mere basics, and does so in a clear, easily understandable manner. It might save us all some time…
A nice effort, but did you notice the date on this thing? Top left says it was written (or maybe even last edited) December 27th, 2005. So, do you think it's a good idea to be referring people to a guide almost two years old? Especially noobies who don't know any better?
