It was between UD and ThePro whose former SZ name was ESH. I didn't get a chance to see it either but apparently it hit a nerve in UD. We are all adults here and if a person's integrity, etc., is questioned or challenged than the normal reaction is to respond to that allegation. My Grandma always said if you can't stand the heat in the kitchen then get out. Apparently ThePro did exactly that. Which, btw, is his right to do if he so desires and is neither seen as a weakness or bad in my opinion, ie., "delete his post". Sometimes deleting a post (although NOT the original thread hopefully), can be quite discrete and recommended in certain situations so as not to compound or accentuate the conflict in question. Hopefully this can all be ironed out eventually.
Best regards,
Mike
