Hi John. I am slightly confused by your comment as you have posted a blog which suggests that you have now visited the site. To be able to post comments you need to 'log in' to the site now that you have registered. This can be done by putting the user name and password that you chose when you registered into the log in box on the left of the page. To post a comment under any of the headings just click on the blue underlined 'comments' under any of the headings. I hope this helps.
