Rather tediously I've managed to
attract an anonymous troll who seems to have been prompted by my previous post.
With blogger, there's an option to ban anonymous posts - some kind of registration is required instead. However I
refrain from that, largely because I want to allow comments to be as
hassle free as possible and I very much welcome feedback even if it is critical.
But it is with some reluctance I've had to turn on comment moderation. This means that while all genuine posts will be published, there may be a slight delay in publication.
I apologise for the inconvenience.
