Welcome, we are happy you are joining us in the battle. i have been using the same approach with the yh as i use with those annoying phone solicitors, a curt goodbye. It is advice i saw in a post somewhere "Thanks yh for stopping by, i am sorry but i am too busy right now to spend any time with you, goodbye!!!" i have never been successful for long at confronting the yh head on, deflecting him is working very well. Go through the handbook and the posts. They have both been helpful to me.
