Comments down, now working again
Sorry, due to an inauspicious conjunction of events comments were not working yesterday.
Event one: moving to Blogger Beta (a mistake, I thought from the way they were trying to encourage me to move that it was out of Beta :(
Event two: a problem at my host - somehow the disk was full, and so not accepting new material, not even comments to the blog!
Event two is fixed, and the new blogger seems to work OK (Barbara has her email back also I hope!
