To run a giveaway on Facebook w/ Rafflecopter, you must go
through a 3rd party iframe application. We recommend Woobox.
Rafflecopter is in no way associated with Woobox, and we will
have an official Rafflecopter FB app very soon.
Step 1: Go to Facebook and search for 'Static
Iframe Tab by Woobox'
Step 2: Click on 'Install Page Tab', choose
choose your page, and click 'Add Page Tab'
Step 3: You'll be taken to the iframe app settings
page titled 'Tab Settings'. Paste the Rafflecopter widget
code in the 'Page Source' area. Make sure the 'HTML' radio button is
selected and your code is pasted in the 'Source' tab.
Step 4: Click 'Save Settings' on the bottom of the page.
You're done!
