My lack of Photoshop, surprisingly enough, has its advantages. I was using GIMP to do a teense of editing on an image to post to the forum (specifically in this thread by LadyEmillye), and I had a eureka-type moment (reminiscent of the Roman bath era), and I'll soon be posting a tutorial explaining said moment in my Guide.
That's right, Rexy's Guide is soon to be GIMP friendly! Yaaayy!!! *Does dance with dog...otter-GIMP-cat-bugeye thing*
