Curveball to the Max!

I'm in an interesting situation now. Just a few days ago, I set up my first discussion forum ("World Wonders, 7 x 6"). It is an extension of a project I did several years ago, in which I created a list of seven natural and man-made wonders for each continent. I hoped that my responders would ask questions about my choices, and even offer choices of their own. I love debating about such things, but, quite frankly, I'm astounded by how fiercely some of them are exchanging blows with each other. I'm trying to stay out of their disputes, only responding on certain factual points, but still, I never really expected anything like what I'm seeing.
