That Was Close!
I almost came a cropper there. I remembered to make the wiki private but had left the blog posts for my S2 project open. A quick Google search by the class and they’d have twigged what I was up to, and some of the answers to their task. I’ll take the protection off again in a couple of days once they’ve formulated some answers.
Until then, if you need access you can contact me at http://about.me/nwinton
