I remember using the function to block people but can't find anything now except "enter the members name" in the control panel edit ignore list. Seems like you could do it from one of their posts.
User lists drops down to add to ignore list. Got you. I won't say thanks sit on my face I don't want anyone to get the wrong idea. : )
Drat it doesn't really work. I was hoping to avoid seeing ads from providers I don't have any interest in. It blocks their message but not their ad/subject. Should be upgraded. I'm sure you'll get right on it.
