Now that the new forum is established and developing a life of its own, we will be closing down the comments section on the Blog tomorrow. Not least, we wish to keep people's comments for prosperity and the existing system deletes them automatically after a fortnight.
For those who do not wish to register on the forum, we have changed the "permissions" to allow people to reply to posts anonymously - as they can with the current commenting system, although they will not be able to start their own threads. Those who do reply without having registered will be identified as a "guest" and they can then decide whether to identify themselves in the text of their posts.
I have also added a new category on "environment", which we hope will become host to an interesting debate.
