The class I taught at the most recent University of Atlantia, "Your First SCA War," is now online at this location. The Web page is an extended version of the two-page handout from class. It's a bit rambling, but it still presents a lot of the information that I was given when I was a newcomer to the SCA and preparing for my first Pennsic War. I hope it aids people who might not have so many kind-hearted advisers in their own local branch.
(I was also motivated to get these notes posted because Master Liam St. Liam of the East Kingdom is thinking of teaching and/or organizing a newcomers' track, and here is something he can link to!)
