I have received 3 replies back from Doc on LinkedIn over the past 18 months. One was personal and the 2 others were UNVC related. He will reply and correspond to concerns and messages that are genuine (maybe a little hint that those who haven't received a response are clearly not genuine.?.)
Petty concerns that most throw at Doc and think are REAL important, aren't.
