I am really saddened to hear this. Mallory joined the board just a few months before I did, and then joined staff just a few months before I did. He was one of the people I enjoyed the most, of all those I have gotten to know on-line.
I almost got the chance to meet him IRL, once, when his work had scheduled him to come to Europe, but then the trip didn't work out. We both said, "Oh, well, it will be another time."
Now there won't be another time.
RIP, Mallory. You will be missed.
