Enjoying a drop of red.
I've no problem with people using the ignore button if that's what they want to do. It's when using the ignore button has an effect on what the other person sees that I have misgivings.I think the key thing is not to cross the threads. As an example many years ago I was arguing with Lunar Scorpion on one thread while helping her on another, as long as the threads stay on topic I see no reason to ignore a person.
And yes, the cross threads thing is a good point.
