Not to be harsh but it sounds like Mark has disappeared from the world in the last year. I have heard that at least 10 of his clients have fired him and that he doesn't respond to emails anymore. I hope he's doing OK because I met him at a conference once and he's nice. Also, you might notice that he doesn't have Facebook or Twitter or a blog. He used to have all three of these things. Until he re-emerges, I wouldn't query Mark.
