I don't really participate on FT anymore, but as you can tell from my post count, I did once, and yes, UP was a part of my experience here, and while I never met him, he was almost always a voice of reason, with the occasional witty barb, like "Still bitter?" LOL He participated in good faith, everywhere you saw him.
I would never suggest I knew him better than those who knew him personally. I would say anyway, that I'm genuinely sorry to hear he passed, and I hope his loved ones know that he was respected and admired here (and probably everywhere he went). RIP, UP.
