I think that must be it. I've tried multiple ways and people to get ahold of him, all to no avail. I was hoping he'd come back in the new year, so for the next few days I will hold out a final hope. But barring that I think we should accept that he's quit and move on. Defcon has already started "replacing" at least one aspect of the Trek Collective in putting up a great release schedule page. Others will surely continue to do the same as time goes on. There really doesn't seem to be anything more to do.
