Tempo Tribe is a youth loyalty website for Mobistar (mobile telecommunications operator). Every one and a half months there's a crazy new offering of goodies, articles, videos, etc, all built around one central theme. This time the theme was winter. To win a salon snowboard (a game snowboard you can hook up to your tv), the members had to practise their yodelling skills by interacting on the site. Then they had to call the Tempo Tribe Yodelline and record their own yodel, the more hilarious, the better. The funniest ones won.
