Get users to nominate their friend for a reward or prize. In this campaign, its all about the consumer. You want to know a story (example: who lost the most weight using our product) and want to get your fans to tell you. This is a great way to capture and engage your audience.
In the details section of the campaign, tell visitors how you plan to use the information they submit. This should provide more context for the story they tell, and will make the stories you receive more relevant for your purpose.
