Not me. I actually mentioned him a few times there. I understand he is a busy man, although I do expect him to at least check out 1 tweet to see who needs help on what, since he advertised that tweet help through the course.

He created this forum so people could ask here, I do think that may be should direct people here if they need to ask a question, but some of the stuff is before this forum excised. (He has replied to post here!). There are lot more to answer your questions here.

I'm not on Twitter, but he did reply to an e-mail I had sent him. It took awhile but he did reply.
