Comments

I've turned off the requirement to register before posting comments to this blog as I realise that the registration process seemed to require you to set up your own blog! (In fact it doesn't but it does look that way.) As you'll see when you click on the 'comment' link you need to type some letters displayed as 'warped' graphics into a verification box before you can post your message. This is to prevent automated 'spamming' of comments on the blog.
