Yes, most members who have been with ISC for a long time will have missed his presence in the forum. Unfortunately, he decided to quit and left in a huff.
To be frank, likely he saw it as "interference" when forum editors were simply doing their job in taking the necessary action as per the editing guidelines. Members are fully aware of the rules and guidelines and should adhere to them. He had done the same on an earlier occasion, too, leaving in a huff for some inconsequential reason, and returning after two years when I contacted him. If he genuinely had an affinity to ISC as he always stated, then he will surely return. Let us wait and see.
