I was just going through the tutorials again, looking for those that I REALY want to try when I actually have the time to put more that twenty minutes on mapping. When I looked through this one (again for the umpteenth time) I noticed a few things that beg the question "what version of Gimp are you using here, or what plug-ins do you have on it?" The two in particular are the Stencil Ops menu and the Gradient Preview you have in the Toolbox beside the Foreground/background display. What does the Screen Ops menu allow you to do? Is it an add on or rolled into a newer version? Where do I find it? ect, ect.

Oh, and Congrats on yet another well deserved scroll.
