Apologies to those that will be inconvenienced by this, but I've had a few abusive comments from anonymous users which I've deleted. As a result, I've decided to cancel the anonymous comment function. Anyone who wants to comment and isn't already a blogger member will have to sign up for a blogger account and use that. Anyone that wants to leave an anonymous and/or abusive comment aren't likely to go to this effort, and will decide not to bother. It's quick and easy, though, and you can use it to log in and comment in future.

Thanks for your understanding.
