You may well wonder where I have been - it's all Google's fault. It locked me out of my blog and whatever I tried I couldn't get in. It helpfully suggested signing out and then in again but every machine I tried on had the wrong user name and wouldn't let me change it. I am now blogging on a very ancient laptop which let me in. This could be my incentive to move to wordpress, which I've heard is better. Anyone able to confirm that?
