Hi all, I am looking to incorporate a slide-over pop-in window similar to what you see here on the New York Times website http://www.nytimes.com/2011/02/03/science/03planet.html?src=ISMR_AP_LO_MST_FB If you scroll down the page, you will find a slide-over window that will be displayed as soon as you reach the last paragraph of the article and will retract back if you scroll up again. Are you aware of any free service that will enable this? Also, any idea how this can be easily implemented on my website? Any help much appreciated.
