Here is an example of adding linked text, such as wall decals, to a post on a blog. You can copy/paste the linked text and add it to a post all by itself, or in the middle of a sentence. Just be sure that the text is linkable and will go to the assigned page when clicked.
After you have entered the linked text, then copy/paste the URL to that post in the blank field in the Giveaways widget on our Fanpage under 'Share Our Site'.
