Several people have contacted me saying their comments are not getting through... I am afraid I have had to turn off anonymous postings to this blog as I have been getting in the order of 2000 blog spam posts *per day* over the past week. Therefore, if you would like to post a comment you will need to sign in to post a message. I'm sorry to do this folks but it seems the only way to ensure that only real people and not spambots are posting to this blog.
Proof you can post a comment when you have signed in!
