I have noticed the same thing since Monk left. My assumption is he had health issues. That's why he left the board for a period of time and then came back for a while and now left again.
I talked to him tonight and last night on the phone. We are good friends. We went to the Troy game together. He has had some health issues but I don't think that's why he stopped posting. I'm sure he will be back posting with us soon. I'll ask him about this next time we talk. He is the best basketball poster I've ever seen on any web site. That's how we became should good friends. He is the best Georgia basketball fan I've ever been around in my 71 years of life.
I don't post a lot, but I do occasionally. Unfortunately I have YouTube TV and haven't had the pleasure (from what I've heard) of watching us play yet.
