My blog changed its appearance. The background went pale green and the text size tiny. I fiddled but I was unable to restore it to its previous fine condition. As I expected, it was nothing I did, just some weirdness caused by a kiddie at blogspot fiddling where he shouldn't have been and it has returned to normal. But my header photo is wrong. Such botheration. I don't have time for fixing other people's errors but I guess will fix it at some point.
Edit one minute later: I thought it had been fixed, but when I checked just now, it is back to being faulty.
