Synopsis

<fb:rock-the-vote ... >...</fb:rock-the-vote>

This tag is interesting because it’s the first FBML tag sponsored by a third party. The year 2008—when this book is being released—is a Presidential campaign and election year, and Facebook decided to offer developers a way to help their users register to vote. So Facebook partnered with Rock the Vote and CREDO Mobile to provide this service though a simple Facebook tag. The tag displays a link on your app that, when clicked, pops up a voter registration form. You can optionally provide a Rock the Vote API key given to you at http://www.rockthevote.com/partners, which allows you to track the number of voter registrations your app has enabled.
