I imagine he has gotten an email alert about it then You can always try pinging the facebook page for the site as well. But I don't believe he is all that active at the moment. Regardless of contact method you may need to sit tight.
Well he did sell off his business. I have a feeling there is a reason for that. Probably to do with time? I never read the announcement. Im not familiar but im guessing this is a newer project of his that he is still pursuing?
Edit: I see he mentioned its on a part time basis.
It's clear he's gone and doesn't want to be contacted. All you can do is follow the instructions on his profile message and hope for the best. Just another example of why I'm not a fan of paying for add ons. Too many people doing this and zero consumer comeback.
