Just disable Javascript and they will go away.

The DEMML project is just getting under way. We don't have a real web hosting service yet so we are just using a free hosting service for now. All you have to do is disable Javascript for this site and you won't see those popups any more. Currently, there is no Javascript anywhere on the site other than those popups so you won't be missing anything other than the annoyance.Most web browsers automatically block popups these days anyway. So just don't turn them on for this site and everything will be fine.
