Popup Script
 

I was thinking about having an advanced popup script made but can't think of many features. The one I do like and comes to mins is the ability to make sure someone who does signup won't get a pop but what other features can you think of that would be pretty cool?

That they blow up your computer after you install them on your site.

Popups are a fucking hell, I had a stupid dll parisate nested in my system folder which was rather popup happy :(
