It would be nice to have a way to load a pop-up (iFrame) "signup/login" window that overlays over the content after a single or combination of criteria is met. Similar to that on Twitter, Facebook, and New York Times .

Examples of (and/or) options:

1. Load "sign-up/login" after _____ seconds on site. (Don't show on policy pages: about, privacy, contact....)
2. Load "sign-up/login" after _____ number of visits to the site over ______ number of days.
3. Load "sign-up/login" after scroll length of ______ by visitor.
4. Load "sign-up/login" after _____ mouse clicks by visitor.
