PS - I am quite excited by the fact that I have, somehow, managed to operate GIMP, this is a total fluke and is entirely beyond my normal set of talents.
PPS - Hobnob got me started with all the GIMP drawingness. He spent a fair chunk of yesterday evening trying to draw what I wanted when I didn't really know. Then I told him I didn't like what he'd done because the text was too dark. This header has only about three things different to the one he drew me - thanks lovely.
