Hi everyone. Just to let everyone know that I probably won't have access to the internet for the next week or two (from tomorrow) as I'm going on a university field course. So while people are free to carry on guessing at this or any of my other puzzles just be aware that you might have to wait quite a while for replies. As soon as I can I'll answer any messages I do have and post a message to say I'm back in any unsolved puzzles. Thanks.
