Thanks everyone for all your comments and theories. I’m sure you’ve noticed that when you make a comment it doesn’t appear instantly, I apologize for this. To cut down on spam I need to approve each comment (and yes there have been some spam attempts). I think I’m doing a fairly good job of keeping up with the comments, although the weekend was a little busy so I didn’t get to all of them until last night. So if you don’t see your comment right away don’t worry about it, I will approve them throughout the day. If you really want to get a good discussion going without the moderation you can head over to the forum where you can post instantly. Thanks again.
