Turns itself off after the campaign, and activates automatically for the next one.
Code is live as soon as you add it, but you'll have to update it for each new campaign.
For most websites: Simply paste the code just below the <body> tag of the page.
Tumblr: Go to your settings by clicking the gear on the toolbar at the top of your Tumblr feed, then hit the 'customize' button under the 'Theme' section. Once on the customization page, click the "edit HTML" button. Scroll through the HTML code looking for the '<body>' tag. Once you find it, paste the code right beneath it, click "update preview" at the top of the code, and then click "save".
Self-hosted WordPress.org blogs/pages: Open up ‘footer.php’ and paste the code above the <body> tag.
